AbstractA modified structure of OTA in CMOS 65-nm with signal- and transient-current boosting is presented in this paper. The structure uses simple cascode current mirrors to overcome channel-modulation effect of the 65-nm MOSFETs and to maintain low-error current matching. Simulations show that the parasitic poles of the OTA in CMOS 65-nm are located at very high frequencies and the achievable bandwidth is much increased with sufficient phase margin to maintain closed-loop stability.
