Charge-pump based switched-capacitor integrator for DS modulators
نویسنده
چکیده
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.

A new organization of switched capacitor charge pump circuits based on voltage doubler structures is presented in this paper. Each voltage doubler takes a DC input and outputs a doubled DC voltage. By cascading n voltage doublers the output voltage increases up to 2 times. A two phase and a multiphase voltage doubler structures are proposed and their properties discussed. The multiphase voltage...
