Architectures and design of OTA/gm-C filters
Yichuang Sun · Institution of Engineering and Technology eBooks · 2002
This chapter has addressed some topics in gm-C filter design. Two integrator loop, LC ladder-based and multiple loop feedback OTA-C filter structures have been studied. Design examples using a wideband high output resistance OTA have been presented. Current-mode gm-C filters have been discussed and compared with voltage-mode counterparts. Tuning issues including both analogue and digital schemes have been discussed.
