Abstract :
Dynamic analog building blocks (integrator, tunable gain stage) with high performance are proposed and analyzed. They exhibit low sensitivities to the component non-idealities (amplifier DC gain, amplifier and multiplier offset voltage, ...) and operate in double-sampled mode. Issues concerning the design of resonator based adaptive filters using the proposed structures are discussed. Numerical results obtained from a proof-of-concept prototype validate the proposed design method
