چکیده
A low-noise CMOS amplifier operating at a 1-V supply voltage is developed using the two noise reduction techniques of autozeroing and chopper stabilization. The proposed amplifier utilizes a feedback with virtual grounded input-switches and a multiple-output switched op-amp. The low-noise amplifier fabricated by a 0.18-μm CMOS technology was measured at a 1-V power supply, and achieved low noise performance of 50-nV/√Hz input noise at 1-MHz chopping frequency.
