A transmitting circuit device has a first signal source which outputs a first signal that is a binary or multilevel discrete analog signal or a discrete analog signal with a binary or multilevel envelope and that has signal components and quantization noise components; a second signal source which outputs a second signal composed of the quantization noise components; a first amplifier which amplifies the first signal; and a combiner which cancels out the quantization noise components by combining an output of the first amplifier and the second signal.
