ABSTRACT

ABSTRACT: Miller compensated OTAs are generally used for frequency stabilization, as with increasing in gain of cascaded OTA the frequency response decreases in terms of gain bandwidth product and phase margin. A positive feedback, to increase the gain at differential stage of OTA is applied which increases gain without decreasing the gain bandwidth product and phase margin. The above prototype is implemented on 65 nm CMOS IBM technology in LT spice using spice model.
