Abstract:
A signal distribution network has segments that each have a buffer circuit, a transmission line coupled to the buffer circuit, an inductor coupled to the buffer circuit through the transmission line, and a variable capacitance circuit coupled to the inductor and coupled to the buffer circuit through the transmission line. A capacitance of the variable capacitance circuit is set to determine a phase and an amplitude of a signal transmitted through the transmission line. A signal distribution network can include a phase detector, a loop filter circuit, and a resonant delay circuit. The phase detector compares a phase of a first periodic signal to a phase of a second periodic signal. The resonant delay circuit has a variable impedance circuit having an impedance that varies based on changes in an output signal of the loop filter circuit.
