Resumen
The design of various current followers for the implementation of OTAs with high slew rate and current efficiency is addressed. Two basic current follower topologies are compared, and modifications of both followers to improve these parameters are presented. As an application example, an enhanced recycling folded cascode OTA is proposed. Measurement results of the OTA fabricated in a 0.5 μm CMOS ...

The design of various current followers for the implementation of OTAs with high slew rate and current efficiency is addressed. Two basic current follower topologies are compared, and modifications of both followers to improve these parameters are presented. As an application example, an enhanced recycling folded cascode OTA is proposed. Measurement results of the OTA fabricated in a 0.5 μm CMOS process show a 260% and 180% improvement in SR and GBW, respectively, for the same power consumption. [--]
