Low-Voltage 0.81mW, 1–32 CMOS VGA With 5% Bandwidth Variations and −38dB DC Rejection

Low-Voltage 0.81mW, 1–32 CMOS VGA With 5% Bandwidth Variations and −38dB DC Rejection

A CMOS low-voltage amplifier with approximately constant bandwidth and DC rejection is introduced. The design is based on the cascade of a wide linear input range OTA, an op-amp and a servo-loop with extremely large time constants. It operates with ±0.45V supplies and a power consumption...
