To avoid output saturation and EOS, we need to limit output swing as much as possible. A lower gain setting can prevent output saturation. Open-loop gain: As any op-amp has a very large open-loop gain, closing the loop is important. Negative feedback is a very easy and common method to achieve stable output,Figure 1-3 shows the saturation region of the MOSFET.

The diode has a 0.7-V drop at 1-mA current,

The Ideal Voltage Transfer Curve is shown in the Fig. 2.7. The curve is not drawn to the scale. If drawn to the scale, the curve would be almost vertical due to large values of op-amp gain. Thus note that the op-amp output voltage gets saturated at +V CC and -V EE and it can not produce output voltage more than +V CC and -V EE.

Assuming 10% resistor values, determine the production gain range for Figure 4.6.1 4.6.In the example shown above, the output voltage is saturated at a value of positive 14.7 volts, just a bit less than +V (+15 volts) due to the positive saturation limit of this …An op-amp operates as an amplifier when the op-amp powered at a voltage between -ve saturation and +ve saturation. This region is called the linear region. When the op amp is saturated then there is no gain. The gain is flat at 0. Hope the following graph will answer your question. Reference:amplitude input signal occurs and causes the output of the operational amplifier to move outside its real capabilities. This saturation can cause large distortion in the application. This document explains how to decrease the output saturation by using a feedback operational amplifier for gain control.

Symbol and associated notation of op-amp The power supply voltages VCC and VEE power the operational amplifier and in general define the output voltage range of the amplifier. The terminals labeled with the “+” and the “-” signs are called non-inverting and inverting respectively. An operational amplifier (op amp) is an analog circuit block that takes a differential voltage input and produces a single-ended voltage output. Op amps usually have three terminals: two high-impedance inputs and a low-impedance output port. The inverting input is denoted with a minus (-) sign, and the non-inverting input uses a positive (+) sign.Some op amps have clamping diodes on the inputs which limit the maximum voltage between the two inputs. This can probably be handled with careful design or by choosing another op amp device. Comparator applications drive the op amp into saturation. Recovery from saturation can be slow and is generally not specified.

Phase-shift oscillator (one op amp) A phase-shift oscillator can be built with one op amp as shown in Figure 6. The normal assumption is that the phase-shift sections are independent of each other. Then Equation 3 is written: (3)The amplifier is then like a normal open-loop amplifier that has very high open-loop gain, and the amplifier is saturated. Thanks to a resistor in parallel of the capacitor, the circuit behaves like an inverting amplifier with a low frequency, and saturation is avoided. 8.
