A High Performance Current-Mode Instrumentation Amplifier For Biomedical Applications

摘要：

In this paper, a high performance current-mode instrumentation amplifier has been proposed for low noise, low power, high CMRR and adjustable gain with an external resistor for various biomedical signal processing. Based on post-layout simulation results, the proposed currentmode amplifier achieves an overall gain of 84.2 dB (PMOS type), 92.5dB (BJ-f type), input-referred noise of 107.7443n VAHz (PMOS type) . 54.940ln VAHz (BJT type), CMRR of 125.3 dB (PMOS type). 121.8dB (BJT type), power consumption of 61.5043 uW (PMOS type). 65.6571 uW (BJT type) at a 1.8-V supply using a standard 0.18-um CMOS technology.
