Abstract :
The effectiveness of using the parallel combination of large-value and small-value capacitors to increase the frequency coverage of either one and overcome the effect of lead inductance is examined. Computed and experimental results are given that show this scheme is not significantly effective. The improvement at high frequencies is at most 6 dB over the use of only the large-value capacitance
