Novel low noise amplifier approach for deep brain stimulation

Abstract This paper presents an analysis for a multi-stage Low Noise Amplifier (LNA) application on deep brain stimulation. A low noise amplifier with high gain, moderate bandwidth and reduced is designed simulated using LT Spice PTM BSIM4 CMOS models. The novel LNA circuit topology proposed which uses cascaded style to improve mid-band gain of LNA. achieves margin ranges between 60-67 (dB), 2X times; Phase Margin 145 154 (deg), 3X Gain 66 75 times from kHz MHz range. current biasing used enhancing stability Also, optimal figure achieved the help cascading input matching along source degeneration technique.
