Abstract :
We describe the first ever reported continuous time, gain enhanced voltage amplifiers which are almost insensitive to mismatch of active devices. Though the proposed approach is general, as a preliminary test we have designed a voltage amplifier in a standard 0.35mum CMOS process; Monte Carlo simulations demonstrate both a significant gain enhancement and its robustness against spread of process parameters.
