Performance tradeoffs of integrated CMOS charge amplifiers

A detailed comparison of integrated CMOS charge amplifiers is presented in this work. Conventional topologies, along with new ones, have been fabricated in a CMOS test chip prototype and their measured performance compared in terms of sensitivity, PSRR, and frequency response. As a result of this work, a complete library of fabricated CMOS charge amplifiers is presented and the performance tradeoffs of each solution discussed. This way the designer can make an educated choice about the design that best suits some given specs.
