The solid-state relay system includes a first solid-state device electrically connected to a first input, the first input electrically connected to a common node. The system includes a second solid-state device electrically connected to a second input, the second input electrically disconnected from the common node. The system includes a set of solid-state devices configured to, based at least in part on a trigger signal, electrically disconnect the first input from a common node and electrically connect the second input to the common node. The first solid-state device, the second solid-state device, and the set of solid-state devices are powered by the first input, the second input, and the trigger signal without using an external power source.

摘要： A system including a source follower circuit is disclosed. The source follower circuit configured as a voltage buffer that includes a first common-drain transistor that passes an input signal at the gate to an output loading capacitor at the source, and a second common-drain transistor that is used as a bias current source. The source follower circuit includes a first resistor at the drain of the first transistor generating a first voltage that is fed back through a first path through the gate of the second transistor so as to produce additional current to help the output signal catch up with the input voltage. The source follower circuit further includes an inductive element and bias circuit, which along with the first resistor, increases bandwidth and reduced settling time.

摘要： A temperature sensor circuit for sensing the temperature of an electronic component is disclosed. The temperature sensor circuit comprises a first transistor configured to be thermally isolated from the electronic component and being configured to sense an ambient temperature and a second transistor configured to be thermally linked to the electronic component and being configured to sense a temperature at the electronic component. The temperature sensor circuit is a differential circuit having a first path and a second path with the first and second transistors being arranged on the first and second paths of the differential circuit, respectively, such that the temperature sensor circuit generates an output voltage inversely proportional to a temperature difference between the ambient temperature and the temperature at the electronic component. The temperature sensor circuit also comprises a shut-off switch configured to activate or deactivate the temperature sensor circuit.

摘要： In one aspect, a solid-state switching apparatus is provided that includes a pair of anti-parallel thyristors, a quasi-resonant turn-off circuit, a sensor, and a control circuit. The turn-off circuit is coupled in parallel with the pair of anti-parallel thyristors and includes a first selectively conductive path and a second selectively conductive path. The sensor is configured to sense a thyristor current conducted by at least one of the pair of anti-parallel thyristors. The control circuit is configured to receive the sensed thyristor current from the sensor and determine a magnitude of the sensed thyristor current and a polarity of the sensed thyristor current. The control circuit is further configured to activate, in response to determining that the magnitude is greater than a threshold value, one of the first selectively conductive path and the second selectively conductive path based on the polarity to commutate and interrupt the thyristor current.
