abstract = "This paper focuses on the design of amplifiers that achieve micro-volt offset by employing dynamic offset reduction techniques, which include chopping, auto-zeroing and chopper stabilization. The working principles and non-idealities of these techniques will be described. The up-modulated offset associated with chopping causes ripple, which can be a significant source of error if not filtered effectively. Thus, various ripple reduction techniques are introduced to suppress this ripple to the micro-volt level. Also discussed is the ping-pong architecture, which enables the realization of auto-zeroed amplifiers with continuous-time behavior. Examples of chopped amplifiers, auto-zeroed amplifiers and chopper stabilized amplifiers are presented, as well as designs in which multiple techniques are combined.",
