WebThe effect of the stray capacitance is to bypass the inductors at high frequencies and thus reduce the amount of delay in the delay line. This in turn narrows the directivity pattern and thus lifts the on-axis response. Although we will describe a method for neutralizing the stray capacitances, it is best not to neutralize all of them in ... WebCoupling and Bypass Capacitors Coupling capacitors (or dc blocking capacitors) are use to decouple ac and dc signals so as not to disturb the quiescent point of the circuit when ac signals are injected at the input. Bypass capacitors are used to force signal currents around elements by providing a low impedance path at the frequency. +-30 kΩ ... WebThe capacitance from collector to base complicates the simple calculation of gain and input impedance. To simplify the problem, we take advantage of the Miller effect (named after John W.
