Ignore PSpice Simulation
Design the MOSFET current mirror shown in Figure 2 to replicate a 1 mA reference current at the drain ofM2. Assume Vtn-1.2 V, L-100 μm, W-100 μm, kh-0.093 A/V2, and V,-100 1. Determine Ri such that IREF 1 mA is the current, Ipi, flowing into the drain of Mi. 2. Calculate lolREF, where lo = 1D2. 3. Simulate the circuit in Figure 2 in PSpice. Use the SEDRA LIB library for the MOSFET transistors and enter the...

10 V IRE R3 Fig. 1: A current source and mirror circuits using npn BJTS Design the current source and mirror circuit in Fig. 1 such that IREF = 10 mA (13%) nominally. Use supply of Vcc = 10 V, and use an average value for ß that you found in your previous experiments or that from the datasheet. Find the value of R, that satisfies the design requirements. In your pre- lab, perform the following: 1....

1. Consider the following current mirror combination, where all transistors have the same kn'(W/L) = kp'(W/L) = 2mA/V2, and VTN-1У, VTP--1V. It is also given that VDD1-10V, VDD2-8V. Remember that for saturation the drain current is given by IDー½ k,"(W/L) (VGS-Yn)" for NMOS and ID ½ kp"(WL) (VGS-V,»)2 for PMOS. You can ignore the channel modulation for all transistors. (a) Find the value of R so that I.-1mA. (b) Are transistors Q1, Q2, Q3 in saturation? (c) What is the...

R, Figure P7.49 .50 Figure P7.50 shows a current source realized using a current mirror with two matched transistors Q, and o, . Two equal resistances R, are inserted in the source leads to increase the output resistance of the current source. If Q, is operating at gm 1 mA/V and has VA-= 10 V, and if the maximum allowed de voltage drop across R, is 0.3 V, what is the maximum avail- able output resistance of the current source?...
