Abstract
Amplifiers utilizing autozeroing suffer from clock spurs at the sampling frequency. This paper describes a method of controlling the clock in order to reduce the amplitude of the spurs in the frequency domain, allowing a wider spurious-free dynamic range for signals with bandwidths approaching or exceeding the sampling frequency. Improvements of 20 dB were measured when using this technique
