摘要： Disclosed is an optically activated microwave switch (10) which includes a field-effect transistor (12) that is switched between conducting and nonconducting states by a photodiode (14) that is connected between the field-effect transistor gate and drain electrode and a photodiode (16) that is connected between the field-effect transistor gate and source electrode. The circuit is configured and arranged for switching unbiased sinusoidal microwave signals of a frequency as high as approximately 10 gigahertz. A cascade arrangement of switches (10) provides increased signal handling capability in situations in which a single switch cannot be employed. Monolithic integrated circuit realizations of both single stage and cascaded stage arrangements are disclosed in which the semiconductor substrate is GaAs, the field-effect transistors are metal-semiconductor field-effect transistors and the photodiodes are interdigitated metal-semiconductor-metal devices.

摘要： A dynamic discharge circuit for a capacitively-charged electrical device includes, in one embodiment, a bipolar transistor placed in the discharge path, with the base of the transistor being connected so that conduction is held off by the voltage generated by an illuminated PV-diode. When the PV-diode is shut off, base-drive is immediately supplied through a base resistor in dynamic fashion by the very capacitive charge that is to be discharged. In another embodiment, the resistor is replaced with a diode-transistor combination, thus eliminating the delaying RC product inherent with the use of a resistor. In yet a further embodiment, an SCR placed in the discharge path is also dynamically driven. Discharge times on the order of about 5 microseconds are attained with the latter two embodiments and it is found that this discharge time is relatively constant regardless of the value of the capacitance to be discharged. Substantially improved charging time of the electrical device is provided in a circuit which includes a phototransistor which supplies charging current derived from the main power supply. The embodiments are described as being applied to the discharge of a capacitively-charged MOSFET in an optically-coupled solid state relay.

摘要： A solid state relay includes a MOS FET receiving a photovoltaic output generated across a photovoltaic diode array responsive to a light signal from a light-emitting element, and a normally ON driving transistor connected to the MOS FET, the driving transistor being connected at control electrode to a connection point between the photovoltaic diode array and an impedance element to be biased by a voltage generated across the impedence element during generation of the photovoltaic output across the photovoltaic diode array to have a high impedance state, whereby the relay can be prevented from providing at output terminals any intermediate state between ON and OFF states even when an input current to the relay is in lower range, and a high speed relay operation is realized.
