Therefore, wideband RF and microwave integrated circuits have become the key enabling technologies for a wide variety of high-speed applications, such as fiber-optic communications, radar, ultrafast instrumentation, and most recently, ultra-wideband (UWB) communications. Compared to their narrow-band counterparts, there are greater challenges in the design and implementation of wideband circuits due to their large bandwidth and stringent noise\/interference constraints. Our research focuses on integrating analog and digital signal processing with RF\/microwave techniques, in order to improve circuit performance and enable reconfigurable wideband circuits.
