This chapter has addressed some topics in g_m-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 g_m-C filters have been discussed and compared with voltage-mode counterparts. Tuning issues including both analogue and digital schemes have been discussed.
