Parallelization and Time Division Multiplexing for 1-bit Bandpass Delta-Sigma Modulator
Takashi Maehata (SEI), Noriharu Suematsu (Tohoku University) SR2022-5
Abstract (in Japanese) (See Japanese page) 
(in English) The 1-bit bandpass delta-sigma modulator (1-bit BP-DSM) outputs RF signals directly from the digital part without using an analog frequency conversion function and local transmitter, thus enabling miniaturization of the transmitter. This paper proposes a configuration that reduces the circuit size by using a 1-bit BP-DSM with time-division multiplexing operation. Moreover, it is also shown that parallel processing can be realized for a multiplexed bandpass delta-sigma modulator to achieve higher speed.
