Abstract
Circuits using differential logic are employed in high-speed optical communications systems. An essential problem in the design of large-scale integrated circuits for this purpose is the control of undesired heat generation, so that the circuits should have low power consumption. According to the invention, a reduction in power consumption is achieved by reducing the number of stages connected in parallel with respect to the power supply. To accomplish this, part of the parallel-connected stages are connected in series with the remaining part of the parallel-connected stages, so that the total number of parallel branches is reduced.
