Basic Current Mirrors If channel-length modulation is neglected, no dependence on process & temperature
Understanding the Context
The current mirror circuits are simple current sources which gives constant current. The current mirror circuits are based on the principle that, if the gate to source voltage of two identical MOSFETs are.
A Wilson current mirror or Wilson current source, named after George Wilson, is an improved mirror circuit configuration designed to provide a more constant current source or sink.
As with the CS amplifier, we can replace the resistor by current mirrors as an active load. Then, a complete differential-input, single-ended output gain stage can be realized.

Key Insights
This lecture deals with the design of current mirrors as both bias elements and signal processing components. Following a review of basic current mirrors, we study cascode mirror operation.
But we can bias it in a narrow regime that gain stay constant for short channel devices.
This lecture covers the design and analysis of passive and active current mirrors in analog circuits, focusing on basic structures, layout issues, high precision mirrors, low-voltage mirrors, and.
