Typically, the ICMR is defined by the common-mode voltage range over which all MOSFETs remain in the saturation region. Output offset voltage (VOS(out)) The output offset voltage is the voltage which appears at the output of the differential amplifier when the input terminals are connected together. Input offset voltage (VOS(in) = VOS) The ...

Thévenin and Norton equivalent circuits are used. in representing the contribution of a circuit to one specific pair of terminals. Usually, a signal is fed into one pair of terminals. (input port), processed by the system, then extracted at a second pair of terminals (output port). It would be convenient to relate the v/i.

We will define the op amp’s input and output CM range in terms of how closely it can approach these two rail voltage limits. At the output, VOUT has two rail-imposed limits, one high or close to +VS, and one low, or close to –VS. Going high, it can range from an upper saturation limit of +VS –VSAT(HI) as a positive maximum.

Line regulation is the output voltage change for a given input voltage change, as defined in Equation 2: Since line regulation is also dependent on the performance of the pass element and closed-loop DC gain, dropout operation is often not included when considering line regulation.

The Bel is a logarithmic measure of a ratio. To make it easier for us to understand, it’s a base–10 logarithm. Typically we use this unit for power ratios. For example the ratio of P2 to P1 in Bels is P2 log. 10 . P1. For example, if P2 = 10P1 the ratio is 1 Bel. This is a rather large unit, so we use decibels instead.

OPEN-LOOP GAIN. Unlike the ideal op amp, a practical op amp has a finite gain. The open-loop dc gain (usually referred to as AVOL) is the gain of the amplifier without the feedback loop being closed, hence the name “open-loop.”. For a precision op amp this gain can be vary high, on the order of 160 dB (100 million) or more.

The MOSFET is by far the most widely used transistor in both digital and analog circuits, and it is the backbone of modern electronics. One of the most common uses of the MOSFET in analog circuits is the construction of differential amplifiers. The latter are used as input stages in op-amps, video amplifiers, high-speed comparators, and many ...

The op amp common-mode rejection ratio (CMRR) is the ratio of the common-mode gain to differential-mode gain. For example, if a differential input change of Y volts produces a change of 1 V at the output, and a common-mode change of X volts produces a similar change of 1 V, then the CMRR is X/Y. When the common-mode rejection ratio is …
