Category:MOS diode-biased cascoded current mirrors

A more popular minimum-size approach for cascode bias in advanced nodes -- where area is at a premium -- is the use of an additional cascode-bias branch composed of a thin diode-connected device which alongside an additional current yields the desired cascode bias. This technique is popular at times when area should be minimized (can not make use of an additional resistor for example), however it comes at the cost of an additional current branch, and due to the use of a thin diode-device a larger variation of the cascode-bias over PVT; suffice it to say, for most applications where area is most important this technique is most preferred.
