High-frequency performance of Schottky source/drain silicon pMOS devices

A radio-frequency performance of 85-nm gate-length p-type Schottky barrier (SB) with PtSi source/drain materials is investigated. The impact of silicidation annealing temperature on the high-frequency behavior of SB MOSFETs is analyzed using an extrinsic small-signal equivalent circuit. It is demonstrated that the current drive and the gate transconductance strongly depend on the silicidation anneal temperature, whereas the unity-gain cutoff frequency of the measured devices remains nearly unchanged

Diode power detector X‐parameters™ model extraction using LSNA‐based measurement system

A study is presented on the problems that may arise when characterising low frequency device behaviour with a large signal network analyser (LSNA)-based measurement system. A diode power detector has been measured and, for the first time, an X-parameters based detector model was extracted from measurements. Difficulties measuring the detector output voltage dependence with baseband impedances, especially when those impedances showed resonant effects, were observed and a method to overcome the problems encountered is presented. The measurement-based detector X-parameters model demonstrated its usefulness to predict power detector behaviour under two-tone excitations and complex loads.Ministerio de Ciencia e Innovación | Ref.

Large-signal waveform acquisition of pulsed signals

Techniques for measuring large-signal waveforms of pulsed signals are fairly well described in the literature. However, most techniques are developed for very specific setups and typically require modification of the hardware. In this paper we describe an approach were no modification is necessary to the existing (Large-Signal Network Analyzer) LSNA hardware and software. Furthermore our method is very well suited for integration with other pulsed stimuli e.g. pulsed IV
