  • (BQ) Tài liệu Signals, Systems, and Transforms is intended to be used primarily as a text for junior-level students in engineering curricula and for self-study by practicing engineers. It assumed that the reader has had some introduction to signal models, system models, and differ-ential equations (as in, for example, circuits courses and courses in mathematics), and some laboratory work with physical systems.

  • This paper presents high-efficiency high-gain 2.4 GHz power amplifiers (PAs) for wireless communications. Two class-B PAs are designed and verified in 0.13 µm CMOS mixed-signal/RF process provided by TSMC. The PAs employs cascode topologies with wideband multi-stage matchings. The singlestage cascode PA is designed for a high power added efficiency (PAE) of 35.4% while the gain is 20.4 dB over the -3 dBbandwidth between 2.4 GHz and 2.48 GHz. The two-stage cascode PA is targeted for a high gain of 37.7 dB while it exhibits a peak PAE of 24.1%. Supplied by 1.

  • Small-signal modeling is a common analysis technique in electronics engineering which is used to approximate the behavior of electronic circuits containing nonlinear devices with linear equations. It is applicable to electronic circuits in which the AC signals, the time-varying currents and voltages in the circuit, have a small magnitude compared to the DC bias currents and voltages.
