WebIn the AZ amplifier, the offset is sampled at frequencies that reach several kHz, so that the resulting technique should be regarded as a real dynamic offset cancellation approach. Figure 1.1 schematically shows the two phases of an AZ amplifier, applied to a voltage amplifier. Let us consider that the amplifier characteristic is given by: t A Webthe body effect will be used to cancel the input referred offset. B. Offset Cancellation Scheme During the offset cancellation phase, comparator inputs are shorted to an appropriate common mode voltage and positive feedback is disabled so that delay can be obtained, C1 and C2 (the capacitors connected to the body terminals of the
WebPrevious designs employed dynamic offset cancellation tech-niques, such as nested-chopping [1], [5], [7] and autozeroing [4], [8], to reduce temperature errors due to the offset of the CMOS amplifiers used in the readout circuitry.
