Can be found in many relevant textbooks covering BJT basics.baby_1 said:Hello
I want to know it we have common Emitter s parameters how can we extract s parameters of common base configuration?if there is no problem give me some examples in converting
Thank you
S parameters, short for scattering parameters, are a set of complex numbers that describe the behavior of a linear electrical network. In the case of a common base configuration, they describe the relationship between the input and output voltages and currents of a transistor.
S parameters allow us to analyze the performance and characteristics of a transistor in the common base configuration. They help us understand how the device responds to different input signals and how it affects the circuit it is a part of.
S parameters are usually measured using a vector network analyzer (VNA). This instrument sends an input signal to the device and measures the resulting output signals at different frequencies. The data is then used to calculate the S parameters.
The main difference between the S parameters of these two configurations is the position of the input and output ports. In common base, the input signal is applied to the emitter and the output signal is taken from the collector, while in common emitter, the input is at the base and the output is at the collector.
S parameters are crucial in the design of common base amplifiers as they determine the gain, stability, and frequency response of the circuit. By analyzing the S parameters, engineers can optimize the design for desired performance and characteristics.
