Design and implementation of sample and hold circuit in ۱۸۰nm CMOS Technology

The most popular approach for realizing analog signal processing in mos integrated circuits is through the use of switch-capacitor circuits. A switched capacitor circuit operates as a discrete-time signal processor. In these circuits(switch-capacitor) the charge on a capacitor is transferred to another Capacitor during a definite time period .Switched-capacitor circuits have many benefit over the continuous -time circuit implementation techniques .the basic building blocks that comprise these circuits. These blocks are the sample-and-hold , gain stage ,integrator,comparator. In this work design a two-capacitor sampel and hold circuit .
