Project Description

I designed a high-gain, low-noise folded cascode fully differential amplifier with Bias-Generation and Common-mode Feedback (CMFB) using 0.18um technology. I started with designing a single-ended amplifier and current mirrors blocks, then pieced them with CMFB to achieve a gain of 56 dB and a signal-to-noise ratio of 62 dB. Phase and magnitude plots along with transient waveforms are shown below.
