  • MOS current mirror capable of operating in the triode region with minimum output drain-to source voltage
    Patent number: 5525927
    Abstract: A circuit includes a first transistor M.sub.1 ; a second transistor M.sub.2 having a gate coupled to a gate of the first transistor M.sub.1 and a source coupled to a source of the first transistor M.sub.1 ; a third transistor M.sub.3 having a source coupled to a drain of the first transistor M.sub.1 and a drain coupled to a current input I.sub.b, the drain of the third transistor M.sub.3 is coupled to the gate of the first transistor M.sub.1 ; a fourth transistor M.sub.4 having a source coupled to a drain of the second transistor M.sub.2, a gate coupled to a gate of the third transistor M.sub.3, and a drain coupled to a supply node V.sub.DD ; and a variable voltage input V.sub.x coupled to the gate of the third transistor M.sub.3.
