Low Noise Low Power CMOS Telescopic-OTA for Bio-Medical Applications

  title={Low Noise Low Power CMOS Telescopic-OTA for Bio-Medical Applications},
  author={Bellamkonda Saidulu and Arun Manoharan and Kumaravel Sundaram},
The preamplifier block is crucial in bio-medical signal processing. The power intensive Operational Transconductance Amplifier (OTA) is considered, and the performance of preamplifier is studied. A low noise and low power telescopic OTA is proposed in this work. To reduce the noise contribution in the active load transistors, source degeneration technique is incorporated in the current stealing branch of the OTA. The OTA design optimization is achieved by gm/Id methodology, which helps to… CONTINUE READING
