Operational Amplifier

An operational amplifier also called op amp is an integrated circuit or analog circuit that takes input as a differential voltage and produces output as a single-ended voltage. It is an IC that can amplify weak electric signals.An op amp has one output pin and two input pins. The basic role of an opamp is to amplify the voltage difference between the two input voltages. It is also used in filtering or to perform mathematical operations or in signal conditioning.

As a maintenance engineer in a semiconductor company, you are given a task to replace the current version of dc-biasing circuit for a faulty tester machine. This dc-biasing circuit used an n-channel JFET as shown in Figure 2. Re-design a new dc-biasing circuit using an n-channel D-MOSFET that can produce a similar output current, IDQ as the previous circuit. Your tasks are: (i) Calculate the operating point (IDQ and VGSQ) of the dc-biasing circuit in Figure 2. Then sketch the JFET network transfer curve (ID and VGS). (ii) Without changing the circuit configuration, calculate the values of source resistor, RS and RB to achieve this objective. Determine the commercial value of the new RS and RB.  For cost reduction reason, the values of RD, RA and VDD should be maintained.  The chosen D-MOSFET has a maximum drain current of 8 mA and gate-source cutoff voltage of – 15V.  The new RS value should be 3 times larger than the old RS used in the JFET network to compensate for the high…
