Here is a close look at the common- versus differential-mode voltage and instrumentation amplifier (IA) topologies.
A Novel Tunable Transconductance Amplifier Based on Voltage-Controlled Resistance by MOS Transistors
Abstract: A new tunable transconductance amplifier is proposed for the programmable analog signal processing or low power filter applications. The transconductor linearization is based on the ...
Abstract: A simple yet effective approach for variable-gain amplifier (VGA) design with accurate dB-linear characteristic is presented. In order to extend the bandwidth of the designed VGA with a ...
