WebLike shunt regulators, here also a part of the output is fed back to the comparator through a sampling circuit where reference input and the feedback signal are compared. So, on the basis of output generated from the comparator, a control signal is generated and it is further provided to the control element on the basis of which the load voltage is regulated. Webfeedback circuit will have (i) a series connection at the input, and (ii) a shunt (parallel) connection at the output. A rule of thumb is: the feedback connection at input matches with that of the basic amplifier, but the connection at the output is opposite to that of the basic amplifier. 4.2.1: System diagrams for the feedback connections
WebFig. 1, shows the voltage shunt feedback amplifier using OPAMP. Fig. 1 The input voltage drives the inverting terminal, and the amplified as well as inverted output signal is also applied to the inverting input via the feedback resistor R f. This arrangement forms a negative feedback because any increase in the output signal results in a ...
