Abstract :
A description is given of the implementation of a low-power, high-performance telephone headset amplifier, using switched-capacitor techniques. Total power consumption is 3.5 mW with a single 5-V supply. Output noise level of -95 dBV has been achieved in both its receiver and transmitter channels. With a single 5-V supply the average area and power consumption per pole of filtering is 510 square mils and 120 μW, respectively
