ABSTRACT:
The sample and hold circuit includes a capacitor and first NPN and PNP transistors for respectively controlling the charge and discharge of the capacitor. The first NPN and PNP transistors are fed with base currents from the second PNP and NPN transistors. The sample and hold circuit further includes a driving controller. The driving controller periodically bypasses the base currents of the first NPN and PNP transistors.
