A design for an instrumentation amplifier with digitally programmable gain and common-mode rejection (CMR) trim is presented. A standard multiplying D/A converter (DAC) is used as the differential ...

So, the open-loop amplifier and the relevant gain equation (Equation 1) — called the transfer function — is shown in Figure 7. The transfer function is simply another way to describe the relationship ...

A 60-GHz digitally controlled phase-inverting variable gain amplifier (PIVGA) is presented, with a gain control range from -9.4 to 6 dB, and a 180° phase inversion. Four digitally controlled nMOS ...
