![]() ![]() Only one of the solutions satisfies the physical constraints in the problem. ![]() ![]() Design the circuit such that the quiescent values are IDQ 250 A and VD 2.5 V. It is based on a depletion-mode MOSFET, using a resistor in the source lead to set the current with the gate-source voltage. Specifications: The circuit configuration to be designed is shown in Figure 3.32 (a). I have used successfully the IXYS IXCP10M45S as a floating two-terminal constant-current device (see Fig 1 of the data sheet cited below). Find every electronics circuit diagram here, Categorized Electronic Circuits and Electronic Projects with well explained operation and how to make it procedure and then New Circuits every day, Enjoy and Discover electronics. Use this value in the gate circuit equation (a) to compute the solution for the source resistance:Ĭomments: Two mathematical solutions are found from the quadratic equation. Objective: Design a MOSFET circuit biased with a constant-current source to meet a set of specifications. Substitute the first value into equation (c) to compute the quiescent drain current: Known Quantities: MOSFET drain and gate resistances drain supply voltage MOSFET parameters V_. ![]()
