Abstract
A method of configuring a switch-network to implement programmable gain devices such as Programmable Gain Amplifiers (PGAs). The method provides high-accuracy and low-distortion with small area requirements and less sensitivity to process and temperature variations when compared with traditional programmable gain architectures where the gain is determined by a ratio between one or more fixed resistors and one or more programmable resistors.
