A low power switched-capacitor (SC) integrator based on a capacitive charge-pump (CP) is proposed. The CP integrator circuit consumes approximately a quarter of the power of a conventional SC integrator while maintaining the same thermal noise performance. Power consumption of the CP integrator is analysed and compared with a conventional parasitic-insensitive integrator. Simulation results verifying the thermal noise and settling performance of the CP integrator are also provided.
