Abstract
Certain aspects of the present disclosure generally relate to a sampling network of a switched-capacitor integrator and a clocking scheme associated therewith, which may be used in an analog-to-digital converter (ADC), for example. The integrator generally includes five sets of switches which allow for a decreased switching frequency (e.g., halved) at an input stage of the integrator compared to conventional double sampling networks. As a result, the input impedance of the integrator may be increased (e.g., doubled), resulting in lower power consumption and reduced strain on driving circuitry.
