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....
