In the capacitively loaded individual transistor inverter demonstrated below, the input voltage is switched abruptly from VCC to 0Volt at time t = 0. In that case the transistor is assumed to function as an ideal change, draw the waveform of the output voltage like a function of time and determine an expression for this voltage. Thus, derive an expression for the low-to-high propagation delay of the inverter within terms of the circuit parameters.
Estimate the maximum tolerable load capacitance when this propagation delay is not to exceed 10ns while βF = 50, RC = 1kΩ, RB = 10kΩ and VCC = 5V.
