This paper presents a wideband CMOS LC voltage controlled oscillator (VCO) with switched current source for 3.4–3.6GHz IMT-Advanced and 4.1–4.8GHz UWB applications. Reconfigurable LC tank with switch control is adopted to accomplish dual band operation and selection. The LC-VCO is fabricated in TSMC0.13μm CMOS process, and fully evaluated on wafer. Bias filters are used in this LC-VCO design to suppress...
In this paper, the design of miniaturized low-pass filter in a Low Temperature Co-fired Ceramic(LTCC) Technology is presented. The pass-band of the low-pass filter is from 900MHz to 1450MHz. The capacitor is constructed by multilayer MIM(Mental-Insulator-Mental) capacitor, and the inductor is fabricated by a narrow metal transmission line. The VSWR of input and output port is less than 1.6. The whole...
Education should be oriented to scientific and practical applications. Therefore, we propose students to study with methods "Learning by Doing", "Project Based Training" and "Solving Problems in an Efficient Way". Through this we introduce them to industry style development work. This paper describes the process how we teach students to learn development activities by...
