ABSTRACT:
Comparator systems are provided that include cross-coupled transistors which respond to a differential network that receives an input signal. The systems further include a control transistor connected across the cross-coupled transistors and a bias network configured to apply a bias voltage to the control transistor that is substantially the voltage across two transistors which are each biased into saturation. It has been found that this bias during the systems' acquire phase substantially stabilizes the systems' gain over variations in their total environment and that this stabilization enhances the systems' performance.
