Abstract
A signal routing circuit is disclosed which employs resistive combiners to reduce signal jitter. A signal routing circuit configured according to an embodiment comprises an input stage including a plurality of buffer circuits. Each of the buffer circuits is controlled by a selection signal to enable an input signal at an input port of the buffer circuit to generate an output signal at an output port of the buffer circuit. The signal routing circuit also includes a plurality of resistors to couple the output port of each of the buffer circuits of the input stage to a summing junction. The signal routing circuit further includes an output stage including an additional buffer circuit. The input port of the additional buffer circuit is coupled to the summing junction, and the output port of the additional buffer circuit is configured to provide the routed output signal based on the selection signals.
