The Z-parameter matrix \[\left[ {\begin{array}{*{20}{c}} {{{\text{Z}}_{11}}}&{{{\text{Z}}_{12}}} \\ {{{\text{Z}}_{21}}}&{{{\text{Z}}_{22}}} \end{array}} \right]\] for the two-port network shown is
An OPAMP-based comparator drives an LED, with V F = 1.6V, the current through which is regulated by a 1 kΩ resistor and a silicon diode in series. Assume a ±10V DC voltage is applied as ±V CC respectively to the op-amp. Then find out the current through the LED when the comparator output is +10V.
The main drawback of JFET is its
