By utilizing the first order behavior of the device,an equation for the frequency of operation of the submicron CMOS ring oscillator is presented.A 5-stage ring oscillator is utilized as the initial design,with differ...
We present an approach of GaAs MESFET incorporating the gate engineering effect to improve immunity against the short channel effects in order to enhance the scaling capability and the device performance for microwave...
The effects of the physical damages induced by heavy ion irradiation on the performance of partiallydepleted SOI devices are experimentally investigated. After heavy ion exposure, different degradation phenomena are o...
A bimodal effect of transconductance was observed in narrow channel PDSOI sub-micron H-gate PMOSFETs,which was accompanied with the degeneration of device performance.This paper presents a study of the transconductanc...

The worst-case radiation effect in deep-submicron SRAM (static random access memory) circuits is studied through theoretical analysis and experimental validation. Detailed analysis about the radiation effect in diff...
A non-micro-air-bridge InP-based heterojunction bipolar transistor (HBT) is fabricated. A very small emitter side etching (〈100nm) is developed and makes a submicron InP-based HBT possible. The current gain cutof...
A novel substrate current model is proposed for submicron and deep-submicron li ghtly-doped-drain (LDD) n-MOSFET,with the emphasis on accurate description of the characteristics length by taking the effects of channe...
Previously,a single data-path stack was adequate for data-path chips,and the complexity and size of the data-path was comparatively small.As current data-path chips,such as system-on-a-chip (SOC),become more complex,m...
