摘要

In this paper, we explore general conditions for the oscillation based test of switched-capacitor biquad filter stages. Expressions describing the characteristics of a filter stage put into oscillation are derived and conditions for achieving oscillation by internal transformation of the filter stage are explored. Reconfiguration scheme based on the transformation of the biquad filter stage to a quadratic oscillator is studied. Theoretically the circuit can be put into oscillation by de-activating a single capacitor. Simulations, however, show that in practice a carefully designed low feed-back loop is required to achieve acceptable oscillation test mode.
