Abstract
The circuit for generating current has a controllable current source M.sub.7, an input transistor pair 24 having a first branch and a second branch, a current mirror 28 having a first branch and a second branch, and an amplifier 50. The controllable current source M.sub.7 is coupled to the first and second branches of the input transistor pair 24. The first branch of the current mirror 28 is coupled to the first branch of the input transistor pair 24. The second branch of the current mirror 28 is coupled to the second branch of the input transistor pair 24. The input transistor pair 24 is coupled between the controllable current source M.sub.7 and the current mirror 28. The amplifier 50 has an output coupled to the controllable current source M.sub.7, and a first input coupled to the second branch of the input transistor pair 24 and the second branch of the current mirror 28.
