Anti-Logarithmic Amplifier. An anti-logarithmic amplifier, or an anti-log amplifier, is an electronic circuit that produces an output that is proportional to the anti-logarithm of the applied input. This section discusses about the op-amp based anti-logarithmic amplifier in detail. An op-amp based anti-logarithmic amplifier produces a voltage ...

The two basic op-amp circuit configurations are shown in Figs. 4.2 and 4.3. Both circuits use negative feedback, which means that a portion of the output signal is sent back to the negative input of the op-amp. The op-amp itself has very high gain, but relatively poor gain stability and linearity.

Remember, the current flowing into an op-amp input is virtually nil, so we can neglect its effect on the voltage divider. This is one of the very nice features of an op-amp. In this circuit, as in the voltage follower, the op-amp works very hard to keep v a - v b very small. Only now v b is a fraction of v o and the op-amp has to make v o that ...
Figure 9.3: Ideal op amp input-output characteristic. There is a simple algorithm for the analysis of an op amp circuit. This algorithm is valid only when there is some path from Vo to V-, i.e., negative feedback is being used to force the op amp to operate in its linear region. (1) Assume that the input currents to the op amp are zero.

the op amp's place in the world of analog electronics. Chapter 2 reviews some basic phys-ics and develops the fundamental circuit equations that are used throughout the book. Similar equations have been developed in other books, but the presentation here empha-sizes material required for speedy op amp design. The ideal op amp equations are devel-
The Op amp's basic operation is that of a difference amplifier, producing a voltage output that is proportional to the voltage difference at its two inputs. These inputs, labelled - (the inverting input) and + (the non-inverting input) form the inputs of an emitter coupled amplifier, a basic example of which is shown in Fig. 6.1.2, it consists

MT-084 the 0-1 transition depends on the value of RL and the stray capacity of the output node. The lower the value of RL the faster, but the higher the power consumption. By using two MOS devices, one P-channel and one N-channel, it is possible to make a CMOS/TTL interface using only two
Ideal Op-amp 1. An ideal op-amp draws no current at both the input terminals I.e. I 1 = I 2 = 0. Thus its input impedance is infinite. Any source can drive it and there is no loading on the driver stage 2. The gain of an ideal op-amp is infinite, hence the differential input V d = V 1 –V 2 is essentially zero for the finite output voltage V o 3.
The name Op Amp comes from "operational amplifier." Op Amp Golden Rules (memorize these rules) 1) The op amp has infinite open-loop gain. 2) The input impedance of the +/− inputs is infinite. (The inputs are ideal voltmeters). The output impedance is zero. (The output is an ideal voltage source.) 3) No current flows into the +/− inputs ...
