Source-Degenerated Frequency of CS Amplifier Formula

LaTeX Go

Source Degeneration Frequency = 1/(2*pi*Time Constant)
f_sd = 1/(2*pi*T_cs)

Why does the frequency in the formula increase when the time constant decreases?

The cutoff frequency is inversely proportional to the time constant in the formula. A smaller time constant implies a faster rate of change in the circuit, allowing higher-frequency signals to pass through. Therefore, as the time constant decreases, the circuit becomes more responsive to higher frequencies, leading to an increase in the cutoff frequency.
