How to Calculate Effective time-constant of the MOS cascode amplifier?
Effective time-constant of the MOS cascode amplifier calculator uses time_constant = (Signal Resistance*(Capacitance gate to source+Capacitance gate to drain*(1+(Transconductance*drain resistance))))+drain resistance*(Capacitance gate to drain+Drain-body Capacitance+Capacitance gate to source)+(1/Load resistance+1/Output resistance)*(Capacitance+Capacitance gate to drain) to calculate the Time constant, The Effective time-constant of the MOS cascode amplifier formula is defined as usually denoted by the Greek letter τ (tau), which is the parameter characterizing the response to a step input of a first-order, linear time-invariant (LTI) system. The time constant is the main characteristic unit of a first-order LTI system. Time constant and is denoted by T symbol.
How to calculate Effective time-constant of the MOS cascode amplifier using this online calculator? To use this online calculator for Effective time-constant of the MOS cascode amplifier, enter Signal Resistance (Rs), Capacitance gate to source (Cgs), Capacitance gate to drain (Cgd), Transconductance (gm), drain resistance (rd), Drain-body capacitance (C_{db}), Load resistance (Rl), Output resistance (Ro) and Capacitance (C) and hit the calculate button. Here is how the Effective time-constant of the MOS cascode amplifier calculation can be explained with given input values -> 495.036 = (1*(2+3*(1+(8*10))))+10*(3+20+2)+(1/1000+1/200)*(3+3).
