Circuit Components 5 G6A02 What type of capacitor is often used in power-supply circuits to filter the rectified AC? A.Disc ceramic B.Vacuum variable C.Mica D.Electrolytic

Circuit Components 6 G6A02 What type of capacitor is often used in power-supply circuits to filter the rectified AC? A.Disc ceramic B.Vacuum variable C.Mica D.Electrolytic Be warned that most large capacitors are of the "electrolytic" type, and they are polarity sensitive! One terminal of each capacitor should be marked with a definite polarity sign. Usually capacitors of the size specified have a negative (-) marking or series of negative markings pointing toward the negative terminal. Very large capacitors are often polarity-labeled by a positive (+) marking next to one terminal. Failure to heed proper polarity will almost surely result in capacitor failure, even with a source voltage as low as 6 volts. When electrolytic capacitors fail, they typically explode, spewing caustic chemicals and emitting foul odors. Please, try to avoid this!

Wire Wound Resistors Many precision resistors utilize a wire-wound construction, where the resistance is determined by the type and length of wire wrapped around a spool. This form of construction allows for high precision of resistance, with low temperature sensitivity if certain metal alloys are used for the wire. Unfortunately, though, wrapping wire around a spool forms a coil, which will naturally possess a significant amount of inductance. This is generally undesirable, as we would like to have resistors possessing only resistance, with no "parasitic" properties. There is, however, a special way in which a wire coil may be wound so as to have almost no inductance. This method is called bifilar winding, and it is common in wire-wound resistor construction.

Stray Capacitance All inductors contain a certain amount of stray capacitance due to turn-to-turn and turn-to-core insulation gaps. Also, the placement of circuit conductors may create stray capacitance. While clean circuit layout is important in eliminating much of this stray capacitance, there will always be some that you cannot eliminate. If this causes resonant problems (unwanted AC oscillations), added resistance may be a way to combat it. If resistor R is large enough, it will cause a condition of anti- resonance, dissipating enough energy to prohibit the inductance and stray capacitance from sustaining oscillations for very long.

Transistor Cases and Insulation Since the TO-220 and TO-247 slugs, and the TO-3 case are connected to the collector, it is sometimes necessary to electrically isolate the these from a grounded heatsink by an interposed mica or polymer washer.

Triode – Three Elements De Forest's Audion tube came to be known as the triode tube, because it had three elements: filament, grid, and plate. The low-voltage AC signal connected between the grid and cathode alternately suppresses, then enhances the electron flow between cathode and plate. This causes a change in voltage on the output of the circuit (between plate and cathode). The AC voltage and current magnitudes on the tube's grid are generally quite small compared with the variation of voltage and current in the plate circuit. Thus, the triode functions as an amplifier of the incoming AC signal (taking high- voltage, high-current DC power supplied from the large DC source on the right and "throttling" it by means of the tube's controlled conductivity).

Tetrode – Four Elements When connected to ground through an external capacitor, the screen had the effect of electro-statically shielding the grid from the plate. Without the screen, the capacitive linking between the plate and the grid could cause significant signal feedback at high frequencies, resulting in unwanted oscillations. The screen, being of less surface area and lower positive potential than the plate, didn't attract many of the electrons passing through the grid from the cathode, so the vast majority of electrons in the tube still flew by the screen to be collected by the plate:

Pentode – Five Elements The suppressor's job was to repel any secondarily emitted electrons back to the plate: a structural equivalent of the beam power tube's space charge. This, of course, increased plate current and decreased screen current, resulting in better gain and overall performance. In some instances it allowed for greater operating plate voltage as well

FET – Field Effect Transistor Uni Junction Transistor All FETs have a gate, drain, and source terminal that correspond roughly to the base, collector, and emitter of BJTs. Aside from the JFET, all FETs also have a fourth terminal called the body, base, bulk, or substrate. This fourth terminal serves to bias the transistor into operation; it is rare to make non- trivial use of the body terminal in circuit designs, but its presence is important when setting up the physical layout of an integrated circuit. The names of the terminals refer to their functions. The gate terminal may be thought of as controlling the opening and closing of a physical gate. This gate permits electrons to flow through or blocks their passage by creating or eliminating a channel between the source and drain. Electrons flow from the source terminal towards the drain terminal if influenced by an applied voltage.BJTsJFETbiasphysical layoutintegrated circuit

RTL IC Logic RTL – Resistor Transistor Logic – The Earliest integrated circuit logic. The obvious disadvantage of RTL is its high current dissipation when the transistor conducts to overdrive the output biasing resistor. This requires that more current be supplied to and heat be removed from RTL circuits. In contrast, TTL circuits minimize both of these requirements.

TTL IC Logic TTL– Transistor – transistor logic contrasts with the preceding resistor– transistor logic (RTL) and diode–transistor logic (DTL) generations by using transistors not only to amplify the output but also to isolate the inputs. TTL devices consume substantially more power than equivalent CMOS devices at rest, but power consumption does not increase with clock speed as rapidly as for CMOS devices.resistor– transistor logicdiode–transistor logicCMOS

CMOS IC Logic Two important characteristics of CMOS devices are high noise immunity and low static power consumption. Significant power is only drawn when the transistors in the CMOS device are switching between on and off states. Consequently, CMOS devices do not produce as much waste heat as other forms of logic, for example transistor-transistor logic (TTL) or NMOS logic, which uses all n-channel devices without p-channel devices. CMOS also allows a high density of logic functions on a chip. It was primarily this reason why CMOS won the race in eighties and become the most used technology to be implemented in VLSI chips.noise immunitypower consumptiontransistors waste heattransistor-transistor logicNMOS logic VLSI
