Abstract :
A fully differential high-speed high-resolution CMOS track & hold amplifier (THA) is designed for CCD analogue front-end (AFE) circuits. First THA structure is described and theorically analyzed in order to extract sub-circuit requirements. Then, low-voltage, high-frequency, low-power, nearly rail-to-rail fully differential 3.3V CMOS op-amp solution, used as THA sub circuit, is described. Finally, conception and implementation of an expected 14-bit, 30-MS/s CMOS THA in BiCMOS 0.35μm 3.3V is developed.
