Abstract
The digitally programmable switched-capacitor equalization filter considered uses a structurally allpass section as a basic building block, allowing for orthogonal tuning of center frequency, bandwidth and gain, through the use of three independent capacitor arrays. Effects of finite gain and bandwidth of the operational amplifiers are investigated. Simulation and experimental results are presented verifying the models involved in the analysis
