Abstract :
A sampled-data feedback circuit topology is presented for the implementation of an enhanced linearity voltage amplifier that does not require an operational amplifier in continuous-time feedback. By oversampling the analog input signal, nonlinearities and gain errors of the internal circuitry are overcome to obtain linearity beyond that of the individual components
