An offset error canceller based on the switched-capacitor technique for realisation of analogue LSIs is developed using a short-channel MOSFET process. Excellent characteristics, such as exceptional capability of suppression of the DC offset component ranging from -3 V to +3 V, large dynamic range of 83 dB and fast operation speed of 2 MHz clock rate, are obtained.
