a) Consider the NMOS circuit given in Fig. 3. Assume VDD = 15 V. Determine the value of RF to set the current IR = 1 mA, using the transistor parameters VTN = 1.2 V, KN = 0.43 mA/V2. Fig. 3. NMOS Circuit b) Add MO and RO to the circuit as given in Fig. 3 as shown in Fig. 4; to form a simple current mirror to be used as a current source. Assume MR and M0 are matched with the same parameters. With VDD = 15 V, and the value of RF as obtained in part (a), and RD = 5 kΩ determine Io and VDSO. Fig. 4. Simple Current Mirror
