Abstract
A novel circulating-delay switched-capacitor (SC) pseudo-N-path (PNP) filter is described which has low sensitivity to finite amplifier gain. The circuit exploits the narrowband characteristic of the PNP filter to predict its output voltage a number of cycles in advance and hence give accurate error compensation.Keywords
