Abstract

A CMOS very high DC-gain telescopic amplifier that uses internal positive feedback technique is presented. The structure of considered amplifier is consisted of rail-to-rail output swing and very high DC-gain. Simulation results predict a DC-gain can be achieved larger than 100dB without limiting the output swing. The proposed amplifier is applied to sample and hold circuit for 10bits 100Ms/s ADC.
