  By Richa Neog, Naushad Manzoor Laskar, Koushik Guha, Saurav Nath, K.L. Baishnab

  Abstract: A microphone preamplifier having low power, low noise and high phase margin for use in hearing aid applications is proposed. The preamplifier uses two-stage topology utilizing self cascode transistors for improving the gain by decreasing the channel length modulation effect and increasing the output impedance. Simulations have been performed in Cadence Virtuoso using SCL 180 nm technology parameters and comparative analysis with other state of art preamplifier design is performed. …
