b. Delay from Vin rising to 1.25V to Vout falling to 1.25V with R = 200 kOhm:




The delay is 1.0135ns.

c. At the point when R is too large, the voltage is increased bringing about a smaller current
moving through the transistor. This will cause a delay in the transistor when the capacitor is
charging or discharging.
