摘要:
A variable-gain amplifier circuit uses a pair of single-ended operational amplifiers to amplify complementary portions of a differential input signal. By using two single-ended amplifiers instead of a single differential amplifier, linearity is significantly improved. In addition, common mode feedback circuitry is eliminated along with harmonic distortion and other forms of noise which tend to negative affect the quality of the signal output from the circuit.
