Note: VDD = VSS = 5V, not VDD = -VSS = 5V
Problem 5: 13 pts The circuit shown below is called a current mirror. Essentially the output curr...
4) Consider the MOSFET differential amplifier shown below, with Io-2 mA, and RL- 10 kS2, Rss-100 k2, VDD- +8V and Vss--8V. The NMOS transistors in the circuit are nominally identical, with kn 2 mA/V2, VTn 1.0 V and ro 100 k2. The PMoS transistors in the circuit are nominally identical, with kp 2 mA/V2, [VTpl 1.0 V and ro 100 kΩ M3 M4 0 M1 M2 a) First consider the DC bias point. Assuming that the current mirror requires at...
These questions refer to the BJT current mirror shown below with Iref = 100 UA (“u” = micro). All transistors have the same ß (beta) and VA given in questions. All output branches go to some load (dashed lines) and then to Vcc = 5 V. The area of each transistor is indicated in the figure: Qı has area “A”, Q2 has area 2A, etc. 5V Iref Io2 Io3 104 R Q2 Q3 Q4 Q1 А 2A 4A 6A Assuming...
