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. These noise reduction techniques using floating analog switches are not suitable for operating at a low supply voltage. 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-m 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. |
