Load Capacitance Effect: Capacitance connected at the output of an operational amplifier is termed Load Capacitance Effect (CL). Figure 15-20 shows that CLÂ is in series with the op-amp output resistance…
Effect of Internal Transistor Capacitance: As we know already that at high frequencies, the coupling and bypass capacitors act as short circuit due to their low reactance and hence the…
Transition and Diffusion Capacitance: Transition and Diffusion Capacitance - Electronic devices are inherently sensitive to very high frequencies. Most shunt capacitive effects that can be ignored at lower frequencies due…
Resonance Bridge for Measurement of Inductance or Capacitance: One arm of this Resonance Bridge, shown in Fig. 11.29, consists of a series resonance circuit. The series resonance circuit is formed…
Stray Capacitance Effects: Stray Capacitance Effects (Cs) at the input terminals of an operational amplifier effectively introduces an additional phase-lag network in the feedback loop, (see Fig. 15-17), thus making…
BJT Cutoff Frequency and Capacitance: Device Cutoff Frequency - All transistors have junction capacitances. The junction capacitances and the transit time of charge carriers through the semiconductor material limit the…
Capacitance of Transmission Lines Articles: Electric Field Inside a Conductor: Imagine an infinitely long straight conductor far removed from other conductors (including earth) carrying a uniform charge of q coulomb/metre…
Capacitance Voltage Dividers: Capacitance voltage dividers are ideal for measurement of fast rising voltages and pulses. The capacitance ratio is independent of the frequency, if their leakage resistance is high…
