Abstract

This chapter begins with the design considerations of switchable opamps for switched-opamp circuits. The derivation of the specifications of a switchable opamp will be discussed. Due to the extra time required to turn on the switchable opamp, the operation speed of a switched-opamp circuit is slower than its switched-capacitor counterpart for a given current consumption. The fundamental turn-on time limit of a few switchable opamps reported in literatures in recent years will be discussed. To improve the turn-on time of a switchable opamp, a novel switching methodology is proposed.
