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...

In low voltage low power CMOS systems both the high input offset and noise voltages of MOSFETs and also the moderate gain of op amps limit the accuracy of analog circuits. In this paper we present a new high-accuracy instrumentation amplifier; this circuit topology is the first ever reported "non-autozero" instrumentation amplifier which allows to compensate, beside the input offset and noise v...

We have developed a method of simplifying physical design for undergraduates enrolled in analog VLSI design. The analog CMOS course is a VLSI design course with laboratory that includes design, fabrication and testing of analog CMOS circuits. A student's design begins with a simple current mirror and ends with different types of sampling circuits such as switched-capacitor and autozero circuits...

A zero-drift amplifier, as the name suggests, is an amplifier with offset voltage drift very close to zero. It uses autozero or chopping technology, or a combination of both, to continuously self-correct for dc errors over time and temperature. This enables the amplifier to achieve microvoltlevel offsets and extremely low offset drifts. Therefore, it is uniquely suited to be used in signal cond...

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 ...
