Task-2 Transfer Characteristics of PMOS Transistor Name: Vasireddy Bharat Sai Reg - No: 16BEC0701

The document describes a procedure to plot the transfer characteristics of a PMOS transistor and determine the threshold voltage. Key steps include designing a circuit with a PMOS transistor, applying DC voltages to the gate and drain, performing DC analysis while sweeping the gate voltage, and plotting drain current versus gate voltage to find the threshold voltage. The threshold voltage was successfully found through this process.
