A sample-and-hold circuit (10) includes a correction capacitor, (CC), a coupling capacitor (CCC), and a primary holding capacitor (CH) connected serially between two ground points.  The common node of the coupling capacitor and the holding capacitor is a held signal node (12).  The common node of the coupling capacitor (CCC) and the correction capacitor (CC) is a correction voltage node (20).  The circuit output is from the signal node (12) through a buffer (14) and a stage selecting switch (SF).  The output is fed back to an operational amplifier (18) whose output is connected to the correction node (20) through a correction sampling switch (SC).  A switched (SA) feedback loop connects the output of the amplifier 18 to the inverting input port.  The primary signal input (IN) is to the signal node (12) through a primary sampling switch (SS).  The noninverting input (+) of the amplifier (26) is connected to the output of a buffer (22). The input of the buffer (22) receives the input signal through an input switch (SI) and is also connected to an input capacitor (CI), which has its other side grounded.

Abstract: ABSTRACT OF THE DISCLOSURE       The invention comprises a pressure actuated switch which is actuated when the inlet port of the device is exposed to a pre-selected pressure.  A piston size, and one or more shear pins, is selected for the desired operating pressure, the piston area being inversely proportional to the desired operating pressure.  Shear pins are preferably of one size and material.  When the desired operating pressure is applied, the force of the piston causes the shear pin to shear thereby allowing an electrical contact to complete an electrical circuit and initiate operation of a selected device such as a recorder, perforating gun, etc.  If a single shear pin is used, with  any selected piston and desired operating pressure, the shear force applied is a constant; i.e., for any given operating pressure and selected piston size with a single shear pin, the applied shear force is the same.  If two shear pins are required, the applied shear force is doubled.  This apparatus provides a switch which will operate over a wide pressure range (approximately 3,500 - 20,000 psi) with a high degree of accuracy and reliability.
