Adaptive digital bias control for an optical receiver and transmitter
This paper presents test results for an adaptive bias control for an optical receiver and transmitter. The need for accurate adaptive bias sources has been an important issue for the design of compact, high-resolution, high-precision optoelectronic circuits. The use of an adaptive bias control is applicable to circuit designs, which require variable bias sources for low power operation or optimal performance. The use of an adaptive bias control for our optical receiver and transmitter enables substantial reductions in the pad count of circuits and are required to optimize the Bit Error Rate of the communications link the circuits operate in. The on chip adaptive bias solution may enable the circuits to be designed with reduced cost, size, and complexity, while maintaining high precision and performance.
