The GRDA1 is 10 GHz to 20 GHz differential amplifier designed on 2 um InGaP HBT process. The gain of GRDA1 is 5 dB typically with flatness of ±3dB over the entire bandwidth. Typical current ... The ...

The op amp — short for operational amplifier — is a packaged differential amplifier. The ideal op amp — which we can’t get — has infinite gain and infinite input impedance. While we can ...

Differential amplifiers are used in myriad applications, including microphones, simulation, analog-to-digital conversion and automatic gain control. See op amp. THIS DEFINITION IS FOR PERSONAL USE ...

Instead it forms a pair of sample-and-hold amplifiers, alternately trimming its own offset as a differential amplifier and then trimming the offset of the other op-amp which does the amplification.
