Abstract: Disclosed is a switch circuit which has a depletion mode n-channel MOSFET which can be used in a circuit allowing only a positive voltage to be supplied thereto, comprising a first D-FET having a gate for receiving an input signal, a drain for outputting an output signal and a source; a first resistor connected between the drain of the first D-FET and a positive voltage source to bias the drain of the first D-FET; a second D-FET having a gate connected to an intermittence controlling voltage source, a drain and a source connected to the positive voltage source and the source of the first D-FET 201, respectively; a second resistor connected between the gate of the second D-FET and a ground to bias the gate of the second D-FET; a constant-current source connected between each of the sources of the first and second D-FET and the ground; a bypass capacitor connected in parallel with the constant-current source and between the drain of the constant-current source and the ground to bypass an RF signal to the ground; and a third resistor connected between the gate of the first D-FET 201 and the ground to bias the gate of the first D-FET. Since the switch circuit can be operated only by a positive voltage without use of a negative voltage, it can be embodied with a general depletion mode n-channel MOSFET which can be fabricated by a relatively simple fabrication sequence and has a relatively simple structure in comparison with an enhancement mode n-channel MOSFET.
