Abstract :
A new current source which is well suited for low voltage applications is proposed. Measured compliance voltage is slightly smaller than that of a single transistor. Its output resistance is a factor of 25 larger than that of a single transistor current source and was measured at 8 MΩ. The use of the new current source improves the common-mode input range and the common-mode rejection ratio of fully-balanced and single-ended differential amplifiers
