摘要: In principle, the upper limit on transistor speed is determined, one hand, by inertia of physical processes taking place in region where charge carriers interact with electric field semiconductor, and, other time it takes to transistor’s output capacitance (which includes load capacitance). This shorter as gain or transconductance higher and magnitudes “ballast” resistances are lower. this chapter we will examine common bipolar transistors (Sec. 1.1) field-effect 1.2) reveal that determine their when operating switches microwave small-signal amplifier mode. From examination fundamental parameters speed. These be used throughout book describe characteristics superhigh-speed transistors. The logic gate presented Sec. 1.3.
