Abstract :
Novel pseudo-N-path (PNP) switched-capacitor (SC) integrator structures which avoid noise peaks in the main passband are described. They combine the simplicity of the previously proposed RAM-type PNP SC circuits with the desirable properties of hybrid-type circuits. Simulation results are presented for filters employing these structures to verify their usefulness.
