Today, two circuit design errors were written. The first one was caused by insufficient current gain. The circuit was triggered by other designers. After reading it, you can learn some knowledge. The main reason for the first error was that the designer incorrectly estimated the size of R1. The value of its design is too large, causing Ib to be too small. Here the equivalent model is converted as follows: The above model describes the model of input and output, and the formal calculation is divided into two parts. Solving the base current Ib Solving the collector current Ic Solve the amplification ratio ETOP WIREHARNESS LIMITED , https://www.oemmoldedcables.com
