Design of Chopper-Stabilized Amplifiers With Reduced Offset for Sensor Applications [PDF]

IEEE Sensors Journal, 2008
Offset error mechanisms in a single-ended chopper-stabilized amplifier are investigated. The error models and their prediction equations are given. This work also presents a new analytical approach for estimating the switch error in a four-transistor chopping network.

Use of Chopper-Notch Modulator in Chopper Amplifiers for Replica Images Cancellation [PDF]

, 2008
— A method for cancelling the replica image limiting the chopper stabilization technique is presented. The modulation of the 1/f noise at the chopping frequency and its multiple are conventionally reduced by a low-pass filter and, possibly by a notch ...
