Investigations of the Electric Field Dependencies of the Generation Rates of Oxide and Interface Traps on Silicon
A bipolar-MOS transistor (BIMOS) is employed to investigate the electric field dependencies of the oxide and interface trap generation and charging on oxidized silicon film on silicon. The substrate emitter/base junction is forward-biased to independently control the current injected into the gate …

Broadband mm-wave signal generation and amplification in CMOS using synthetic impedance
… between the drain voltage and drain current of a MOS transistor. A high frequency, wide tuning range 105-121GHz oscillator and a small-footprint 20-40GHz oscillator using synthetic resonance are presented. The concept of impedance synthesis is also used to generate a novel frequency-adaptive loss …
