Abstract :
A monolithic chopper amplifier system has been developed that reduces the effective offset voltage of an NMOS operational amplifier to a few microvolts without compromising bandwidth. Internally, two amplifiers are used, connected in a switched feed-forward configuration. The system is realized in a standard silicon gate enhancement/depletion process.
