  1. How does a current mirror work? - Electrical Engineering Stack …

    May 6, 2023 · A current mirror consists of two cascaded "mirror" converters with heterogeneous inputs and outputs - current-to-voltage and voltage-to-current. The result is a current-to-current …

  2. transistors - Current mirror: real-life examples? - Electrical ...

    Jan 24, 2021 · I'm looking for examples of how current mirror is used in real life. Most tutorials cover the circuit itself but don't go into examples. Therefore, I'm still struggling to understand …

  3. current - Wilson mirror operation - Electrical Engineering Stack …

    Dec 20, 2024 · In a simple current mirror, the output current is smaller than the input current by "two base currents" (Iout = Iin - 2Ib). In the Wilson current mirror, an additional transistor takes …

  4. mosfet - Why won't this new current mirror work? - Electrical ...

    Oct 9, 2024 · A current mirror is a perfect current-to-current converter whose input maintains a constant voltage and whose output maintains a constant current. Therefore, we can drive it …

  5. Why do we use current mirrors? - Electrical Engineering Stack …

    Sep 11, 2016 · Current mirrors take a positive current (source) and generate a negative current (sink). Current mirrors have low input impedance, so the 'reference' current can be from a poor …

  6. circuit design - Cascode current mirror transistor biasing

    May 26, 2023 · I'm having trouble intuitively understanding how a MOSFET cascode current mirror functions. I understand that the purpose of M3 is to shield M2 such that variations in …

  7. Why does current mirror need a diode connected configuration?

    Oct 6, 2023 · A similar question to this is asked here but it is BJT based current mirror and the answer is there would be no path for base current: Why use diode connected BJT (and not just …

  8. How to solve current mirror with emitter degeneration

    Jun 14, 2024 · How to solve current mirror with emitter degeneration Ask Question Asked 1 year, 7 months ago Modified 1 year, 6 months ago

  9. [SOLVED] - wide swing cascade current mirror design the ratio of …

    Feb 9, 2020 · Cascode and mirror devices don't have to have the same size. Fix the Vov of the mirror device, say 200mV or 150mV and plan to have maybe 20-30mV on top of it for the Vds …

  10. operational amplifier - Current mirror with mosfets - Electrical ...

    Aug 11, 2020 · This is a current mirror circuit with 2 op amp stages. First stage on the left Voltage from a DAC gets fed into U1 which creates a reference current through Rmir (via the N …
