Chopper stabilization in analog multipliers
… offset in multipliers is studied in isolation. Chopper stabilization, a technique long used in DC amplifiers, is applied to analog multipliers to achieve the lowest offset reported.

Study of chopper stabilization in single ended amplifiers
Chopper stabilization is one of the prominent techniques used to overcome low-frequency noise and DC offset errors in CMOS amplifiers. This thesis presents a detailed analysis of this approach. The fundamentals of chopping, followed by the design and underlying tradeoffs of a chopper stabilized …

Nested chopper stabilization in analog multipliers and mixers
… architecture for analog multiplication using chopper stabilization. Chopping is used to modulate the offset away the output signal where it can be easily filtered out, providing continuous offset reduction which is insensitive to drift. Both square wave chopping and chopping with orthogonal …

Low-power amplifier chopper stabilization for a digital-to-analog converter
… much less capacitance than the SC filter. Chopper stabilization is applied to the amplifier to reduce the low-frequency noise. The challenge of this architecture is maintaining amplifier harmonic performance and transient performance. In simulations, chopper stabilization improved …

High performance amplifier topologies implemented with a micro-machined vibrating capacitor
… via the use of correlated double sampling or chopper stabilization. At the system level, this amplifier consists of two major loops: the drive loop and a sense loop. The drive loop includes half of the MEMS structure along with some electronics and provides a means of moving the beam at a …
