Abstract
A 1-bit D/A conversion circuit according to the present invention comprises an RZ signal generating circuit and a PRZ signal generating circuit. The RZ signal generating circuit receives 1-bit digital data sampled at a predetermined frequency, converts the digital data into a first RZ signal and a second RZ signal complementary to the first RZ signal, shifts the first and second RZ signals with respect to each other by an integral multiple of the predetermined frequency, which is greater than one, and outputs these RZ signals. The PRZ signal generating circuit receives the first and second RZ signals, combines these signals together, and outputs a signal which is a type of a PRZ signal.
