This is eventually limited by the input capacitance of the valve, which sets a limit on how high the signal impedance can be made if a certain bandwidth is desired.

The amount of bypass capacitance must be carefully matched with the input capacitance of the oscilloscope so that the capacitors also form a 10x voltage divider.

If the second stage has an effective input capacitance and voltage gain , then slew rate in this example can be expressed as:

A phenomenon known as the Miller Effect causes the input capacitance of an amplifier to be the product of Cag and amplification factor of the valve.

Power converters also often have inrush currents much higher than their steady state currents, due to the charging current of the input capacitance.

The CDTA is free from parasitic input capacitances and it can operate in a wide frequency range due to current mode operation.

If each device has 8 pF of input capacitance, then only 11 pF of trace capacitance is allowable.

In some cases, however, the gate inductance and the input capacitance of the transistor can constitute an oscillator.

While it has high speed due to low input capacitance, it has only limited capacity to drive a load.

The gate-drain capacitance is effectively multiplied by the factor , thus increasing the total input capacitance and lowering the overall bandwidth.
