A Miller Compensated Gain & Phase Enhanced Two-Stage Differential OTA's Using Positive Feedback At Differential Stage
نویسنده
چکیده
ABSTRACT: Miller compensated OTAs are generally used for frequency stabilization. With increasing in gain of cascaded OTA the frequency response decreases in terms of gain bandwidth product and phase margin. To increase the gain at differential stage of OTA, a positive feedback 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 spic model.

A Novel Active Feedback Frequency Compensation Scheme for Two-Stage OTA
A novel active feedback frequency compensation scheme is presented in this work. Based on the proposed technique, an amplifier with two main poles in its frequency bandwidth can be easily compensated by introducing a pole-zero pair in a local feedback. The proposed method is mathematically analyzed and then based on the derived formulations, a design procedure is established. The capability of ...
