Abstract :
A novel predictive switched-capacitor amplifier stage is described. It is a track-and-hold amplifier which uses a minimum number of additional capacitors to desensitize the operation to amplifier imperfections. Simulations indicate that the proposed circuit has smaller gain error and lower harmonic distortion than those described in earlier work.
