ABSTRACT:
An FET sample and hold switching circuit with low transient feedthru in a sample and hold phase detector. The FET OFF voltage is clamped to a value well below the supply voltage thus permitting reduction of stored charge on the interelectrode capacitances. This combined with FET capacitance compensation provides substantial reduction in feedthru and switching transients.
