All-digital cost-efficient CMOS pulse-expanded temperature sensor with digital set-point programming

This study presents a cost-efficient complementary metal-oxide-semiconductor (CMOS) pulse-expanded temperature sensor (PETS), which is the first all-digital time-domain temperature sensor (TS) architecture to feature digital set-point programming. The design utilizes a shared core and pulse expansion to achieve a highly compact structure. Unlike conventional time-domain TS's with digital set-point programming that require dual-core architectures, the PETS significantly reduces hardware complexit
