Introduction The bipolar junction transistor was the first solid-state amplifier element and started the solid-state electronics revolution. An SSR has delay times called the operating time and release time. The sandwich’s resistance is much lower than that of straight polysilicon. Explain why. From the above discussion, we can say that by operating the transistor in saturation and cutoff region, we can use the transistor as an ON/OFF switch. Although transistor switching circuits operate without bias, it is unusual for analog circuits to operate without bias. EPITAXIAL PLANAR TYPE (PCT PROCESS). CMOS technology combines both n-channel and p-channel MOSFETs to provide very low power consumption along with high speed. Anything more than 5mA will kill the Transistor; hence a resistor is always added in trasistor with base pin.
