A wideband, fixed gain BiMOS amplifier

Circuits which achieve precise gains without the use of negative feedback have recently become of interest because of their simplicity and large bandwidth. A new circuit architecture is proposed for precision, fixed gain amplifiers using an open loop approach. Two circuit implementations using the new architecture are presented. The first is constructed as a 9 /spl times/ 12 mil cell on an N-well CMOS process with a combination of MOS and bipolar devices. The second is constructed on a standard linear bipolar process using a semicustom array.<
