Performance sensitivity to feature size
1 Input analog bandwidth limitations: - IO pads ESD protections Yes (RF diodes) + - Effective input signal load (R, L, C) No - Open switches parasitics Yes + 2 Sampling process - Switch resistance Yes + - Storage capacitance value No (kT/C limited) - Number of caps at a time No (constant ~ 4) - Aperture jitter Yes - Dynamic range Yes Voltage supply dep .-
