A great deal of progress has been made in op amp DC characteristics. Carefully executed designs currently available provide sub-microvolt VOS ΔT drift, low bias currents and open-loop gains exceeding one million. Considerable design and processing advances were required to achieve these specifi cations. Because of this, it is interesting to note that amplifi ers with even better DC specifi cation were available in 1963 (Philbrick Researches Model SP656). Although these modular amplifi ers were large and expensive (≈3" × 2" × 1.5" at $195.0

Application Note 79 IC Preamplifier Challenges Choppers on Drift
Since the introduction of monolithic IC amplifiers there has been a continual improvement in DC accuracy. Bias currents have been decreased by 5 orders of magnitude over the past 5 years. Low offset voltage drift is also necessary in a high accuracy circuits. This is evidenced by the popularity of low drift amplifier types as well as the requests for selected low-drift op amps. However, until n...

متن کاملDesign of accurate analog circuits for low voltage low power CMOS systems
In low voltage low power CMOS systems the high input offset and noise voltages of MOSFETs and the moderate gain of op amps limit the accuracy of analog circuits. In this paper we summarize the results ofour recent research on the dynamic op amp matching which is a very attractive technique for the implementation of accurate analog circuits in low voltage low power CMOS systems because, in compa...
متن کاملElectronic interface for the accurate read-out of resistive sensors in low voltage–low power integrated systems
The accuracy of integrated sensors is often limited by errors of the electronic interface; this is the case in most low voltage–low power integrated sensor systems. In this paper we describe the dynamic op amp matching (DOAM) technique; the circuits using the dynamic op amp matching (DOAMCs) are a new type of circuits using dynamic element matching (DEMCs). In comparison with traditional DEMCs ...
