Abstract—This paper presents a delta-sigma pulse-width digi-
tizer ( /1/6-PWD) architecture designed for a super-regenerative
receiver (SR-RX) operated at the 400-MHz Medical Implantable
Communications Service (MICS) band. The
/1/6-PWD em-
ploys the operation principle of a /1/6 modulator to convert
the pulse-width (PW) value into digital domain and achieve fine
resolution, which allows the SR-RX to support the 2-ASK/4-ASK
modulations. It can be considered as the PW d
