Abstract
The letter describes a single stage operational transconductance amplifier (OTA) with cascoded output transistors, designed for micropower switched-capacitor filters. The device features high voltage gain (>90 dB) under capacitive load, large output swing, very low power consumption (5 ¿W at 3 V supply voltage for 100 kHz bandwidth with 10 pF load) and reduced circuit area (<0.1 mm2).
