Abstract
Abstract A sampling diode bridge circuit in which the sampling diodes of the bridge are reverse biased until rendered conducting by the presence of sampling pulses wherein the reverse biasing voltage for the sampling bridge diodes is created by the sampling pulses and wherein means including a parallel combination of a zener diode and capacitor in series with a resistor in one of the bridge diagonals regulates the reverse biasing voltage during the interval between sampling pulses. The invention described herein may be manufactured, used, and licensed by or for the Government for Governmental purposes without the payment to me of any royalty thereon.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
126 words
A sampling circuit comprising a diode bridged having two pairs of oppositely disposed terminals one of which is receptive of input signals to be sampled; supply means including capacitor means for applying periodically recurring sampling signals to the other of said terminal pairs, and bias means for regulating the reverse bias for said diode bridge during the interval between said sampling pulses; said bias means including said capacitor means, the parallel combination of a voltage regulator device and a capacitor disposed in the bridge diagonal interconnecting said other terminal pair in shunt with said sampling signals, and a diode in series with said shunt connected capacitor and voltage regulator device in the aforesaid bridge diagonal; said diode conducting only during the intervals between said sampling pulses.
Claim 2
Dependent Claim
