Dynamic Range of Low-Volt age Cascode Current Mirrors Erik Bruun and Peter Shah’ Electronics Institute, Bldg. It is desired to generate two currents equal to 50uA and 500uA from a reference of 200uA. LOW VOLTAGE CURRENT SOURCES AND BIAS CIRCUITS In this report, low voltage current mirror bias circuits are discussed and the their corner simulation results are given.


In order to suppress the effect of channel length modulation, a cascode current mirror can be used. A feedback loop is used to stabilize the output current. A novel low voltage self-biased high swing cascode current mirror (SHCCM) employing bulk-driven NMOS transistors is proposed in this paper. 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. 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. 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.

349 Technical University of Denmark DK-2800 Lyngby Denmark Tel. In proposed structure cascode stage is used to enhance the output impedance of existing regulated cascode current mirror. For basic current mirror, we can modify the equations by considering channel length modulation. All coming from a source of 0.2mA. In Figure 1, used low voltage cascode current mirror circuit is shown. 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. The voltage V b is obtained using different bias circuits and it is chosen as minimum as possible. We can write, While VDS1 = VGS1 = VGS2, VDS2 may not be equal to VGS2 because of the circuitry fed by M2. Design the current mirror In this paper, a novel regulated cascode current mirror is proposed. 4.
