Switched capacitor integrator

Neat black-and-white schematic of a switched-capacitor integrator centered on a right-pointing operational amplifier triangle. A feedback capacitor connects from the op-amp output back to the inverting input. The input resistor is replaced by a sampling capacitor and clock-controlled switches: one capacitor is alternately connected by MOS-style switch symbols between the input node and the op-amp’s virtual-ground inverting-input node under two clock phases. Include clearly drawn capacitor plates, distinct switch elements, and a grounded reference connection as appropriate for the switched-capacitor network. Clean circuit-diagram line art.
