Özet

A novel charge sharing switched capacitor integrator is proposed in this paper. It is mainly based on reducing the effective input sampling capacitance, such that the integration capacitance can be chosen much smaller while maintaining the same sampling to integration capacitance ratio. Reducing the integration capacitance will result in less integration current and less integration current will in turn result in less power over the integrator which is the main goal of this work, reducing the integrator power consumption and chip area. Another main advantage of this configuration is, that it can be used in large time constant integrators without using physically large integration capacitance. © 2010 by Department of Microelectronics & Computer Science, Technical University of Lodz.
