A new method for kTC noise analysis in periodic passive switched-capacitor networks

Abstract

This work presents a new method for kTC noise calculation in periodic switched capacitor circuits. Two basic applications are overviewed. Namely the switched capacitor low-pass filter and the N-path band-pass filter. Analytical noise calculation using the new method is performed for both examples. The obtained analytical results are confirmed with SpectreRF Pnoise analysis and ELDO transient noise simulations.
