Design the current mirror The comparison with the conventional circuit reveals that the proposed bulk-driven circuit operates at lower voltages and provides enhanced bandwidth with improved output resistance. For basic current mirror, we can modify the equations by considering channel length modulation. A feedback loop is used to stabilize the output current. CH 9 Cascode Stages and Current Mirrors 38 Example 9.15 : Different Mirroring Ratio Using the idea of current scaling and fractional scaling, Icopy2 is 0.5mA and Icopy1 is 0.05mA respectively. In proposed structure cascode stage is used to enhance the output impedance of existing regulated cascode current mirror. In Figure 1, used low voltage cascode current mirror circuit is shown.

Current and Voltage Sources 2 Analog Design for CMOS VLSI Systems Franco Maloberti Current mirrors A current mirror gives a replica (attenuated or amplified, if necessary) of a bias or signal current. modifications consist of using a wide-swing current mirror to help deal with output voltage issues stemming from high threshold voltages in the silicon carbide process, as well as using a modification that allows for an increased input common mode range. We can write, While VDS1 = VGS1 = VGS2, VDS2 may not be equal to VGS2 because of the circuitry fed by M2. It is desired to generate two currents equal to 50uA and 500uA from a reference of 200uA. All coming from a source of 0.2mA. The voltage V b is obtained using different bias circuits and it is chosen as minimum as possible. 349 Technical University of Denmark DK-2800 Lyngby Denmark Tel.
