发明名称 Differential reference signal distribution method and system
摘要 In a reference signal distribution system, a first subsystem is configured to distribute a reference signal to a second subsystem. The first subsystem includes multiple diode-connected devices biased by a reference current and configured to establish a differential voltage between a first node and a second node. The second subsystem includes multiple diode-connected devices driven by the differential voltage and configured to generate a copy current associated with the reference current.
