Abstract/Summary
Frequency-modulated continuous wave radars are a type of radar capable of measuring the distance to a stationary object or velocity of a moving object by radiating a continuous transmission of a signal that linearly sweeps its frequency repeatedly between two set frequencies. Frequency-modulated continuous wave radar signals are generated by a high frequency voltage-controlled oscillator or digital-to-analog converter. This project is an integrated circuit that produces the frequency-modulated signal on a single chip in the analog realm. The circuit was designed using Cadence Virtuoso with TSMC 180 nm process technology model. The generated signal is intended for use with ultra-wideband radars, so it must have a bandwidth larger than 500 MHz, operate in the frequency range between 3.1 GHz to 10.6 GHz, and have a highly linear sweep characteristic. The design targeted a bandwidth of 1 GHz and frequency range of 3.2 GHz to 4.2 GHz and the resulting design has a bandwidth of approximately 980 MHz and range of 3.228 GHz to 4.208 GHz.
