WebApr 30, 2024 · This is the dominat impedance loading the collector of the first stage and reduces RC1 to an equivalent of 456 ohms. This means that the gain of the first stage (with the 2nd stage connected and loading) is about 456/8.6 = 53. For the 2nd stage, r E is 5.6 ohms and RC2 is 1,000 10,000 hence its gain is 909/5.6 = 162. WebThe primary purpose of a BJT is to amplify the current. This allows BJTs to be utilized as amplifiers or switches in electronic devices such as cell phones, industrial control, television, and radio transmitters. NPN (a BJT made from n-type, p-type, and n-type semiconductors) and PNP (a BJT made from p-type, n-type, and p-type semiconductors ...
