Capacitively-Coupled Chopper Amplifiers by Qinwen Fan, Kofi A. A. Makinwa, Johan H. Huijsing

By Qinwen Fan, Kofi A. A. Makinwa, Johan H. Huijsing

This publication describes the idea that and layout of the capacitively-coupled chopper method, which are utilized in precision analog amplifiers. Readers will learn how to layout power-efficient amplifiers applying this method, that are powered through normal low offer voltage similar to 2V and probably having a +/-100V enter common-mode voltage enter. The authors supply either uncomplicated layout strategies and distinctive layout examples, which hide the world of either operational and instrumentation amplifiers for a number of functions, rather in strength administration and biomedical circuit designs.

Sample text

The slew rate of the circuit, however, may be limited by Gm2 and Cm21,2. Thus, to enhance the slew rate, the output current that Gm2 is able to deliver must be optimized. However, the same story also applies to Gm1, since a signal current is required to charge Cm1,2 as well. 2 Input Chopper Several floating choppers with beyond-the-rail CMVR have been introduced in Chap. 4: two small-signal topologies (Figs. 8) and a large signal topology (Fig. 9). For a CCOPA, the input differential signal is always small since its input will serve as a virtual ground.
