High accuracy programmable gain amplifier

摘要

A high accuracy programmable gain amplifier has reduced temperature dependency, reduced supply voltage dependency, and supports accurate amplifier gain and accurate amplifier gain steps. The high accuracy programmable gain amplifier allows requirements compliant electronic devices to be fabricated that are capable of providing improved operational performance with less power consumption, hence extended battery life and improved operational availability. Electronic devices that incorporate the high accuracy programmable gain amplifier described below, may experience reduced variations in operational performance resulting in a reduced need for post production calibration, reduced calibration data storage requirements, and reduced device control processor cycles for use in performing calibration operations, thereby allowing such devices to be produced at a lower cost and/or to provide users with increased operational performance and/or increased battery life and, hence, increased operational availability.
