Abstract
Presented in this paper is the design of an accurate CMOS current source for low voltage current-mode transmitter drivers. It is composed of binary weighted current mirrors and built-in-self-test (BIST) structures for self-measurement and calibration. The current source can achieve ±0.5% accuracy, despite of transistor mismatch, power supply and temperature variations
