ABSTRACT:
A cascode connection circuit includes a first field effect transistor (FET) which has a source terminal and a drain terminal, the source terminal being connected to ground; a second FET which has a source terminal and a gate terminal, the source terminal being connected to the drain terminal of the first FET; and a first resistor and a first capacitor connected in series between the source terminal of the first FET and the gate terminal of the second FET. The first FET and the second FET are cascode-connected to each other. The product of the resistance of the first resistor and the capacitance of the first capacitor does not exceed 0.1 times the period of an operating frequency of the circuit.
