Patent number: 9912301Abstract: Amplifiers can be used for a variety of electronic-based applications. Therefore, amplifier performance is of importance. A low noise amplifier can be interfaced after an antenna or a band-select filter as a first active stage, in a receiver since its bandwidth characteristics can be closely related to a system data rate. A bandwidth enhancement technique can be leverage for low noise amplifiers by embedding a transformer between a gate and a drain terminal of a common gate transistor in a cascode topology. The embedded transformer can introduce an additional high-frequency conjugate zero pair, which can push the gain rolling-off start-up point to a higher frequency, peak the higher frequency gain, and broaden the low noise amplifier gain bandwidth.Type: GrantFiled: April 12, 2016Date of Patent: March 6, 2018Assignee: CITY UNIVERSITY OF HONG KONGInventors: Quan Xue, Pei Qin, Kam Man Shum
