Abstract
A 12-band microprocessor-controlled graphic equalizer display filter IC, designed for use in audio applications, is described. The device is implemented in a 2-micron CMOS process and utilizes switched-capacitor technology to replace several discrete components (op amps, resistors, capacitors, and diodes) and multiplexers. The chip occupies 18000 square mils and dissipates 100 mW
