ABSTRACT:
A capacitor is connected between the gate of an FET and an input node, and a resistor is connected between the input node and a ground terminal, thereby preventing the FET from oscillating in a low-frequency domain. A capacitor is connected between the drain of the FET and a ground terminal, or a line and a capacitor are connected in series between the drain of the FET and a ground terminal, thereby preventing the FET from oscillating in a high-frequency domain or at a specific frequency in the high-frequency domain.
