This paper presents a radar system for extracting human respiratory features. The proposed radar chip comprises three major components: a digital-to-time converter (DTC), a transmitter, and a receiver. The all-digital standard cell-based DTC achieves a timing resolution of 10 ps on a 100-ns time scale, supporting a range-gated sensing process. The transmitter is composed of a digital pulse generator...
This paper proposes a novel design method for single-phase inverter controller with complex programmable logic device (CPLD). With the development of electronics science and technology, CPLD is becoming one of the most popular solutions for the design of control unit with complex function and algorithm. CPLD has a lot of advantages, such as high speed, flexibility control and convenient programming,...
