MOSFET Current Sources Learning Outcome: o To analyze and design a basic two-transistor MOSFET current-source circuit with additional MOSFET devices in the reference portion of the circuit to obtain a given bias current. o To analyze and design more sophisticated MOSFET current-source circuits, such as the cascode circuit, Wilson circuit, and wide-swing cascode circuit. o To analyze the output resistance of the various MOSFET current-source circuits and design a MOSFET current source circuit to obtain a specified output resistance.

4.0) FET Integrated Circuit Biasing Field-effect transistor ( FET ) ICs are biased with current sources in the same way as bipolar circuits . Problem-Solving Technique Analyse the reference side of the circuit to determine gate-to-source voltages. Using these gate-to-source voltages, determine the bias current in terms of the reference current. To find the output resistance, place a test voltage at the output node and analyse the small-signal equivalent circuit. Keep in mind that the reference current is constant, which may make some of the gate voltages constant or at ac ground.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
