摘要： A high speed totem pole FET driver circuit with differential cross-conduction prevention. The driver circuit includes first and second switching elements coupled to a first node, and third and fourth switching elements coupled to a second node. The first node is coupled to a first current source, a pulldown circuit, and the input of the third switching element. The second node is coupled to a second current source, a pullup circuit, and the input of the second switching element. Trigger inputs are applied to the inputs of the first and fourth switching elements to switch the first and fourth switches ON and OFF, wherein the two trigger inputs are of opposite phase so that when one input is HIGH (LOW) the other input is LOW (HIGH). The second switching element may include a comparator circuit with its non-inverting input coupled to the second node, its inverting input coupled to a power source via a V.sub.BE circuit, and its output coupled to a fifth switching element, where the fifth switching element is coupled to the first node.

摘要： Techniques for reducing noise generated by a circuit include a common mode filter and a differential mode filter. The common mode filter includes an input for sensing a common mode signal between a power source and the circuit, an output, and active circuitry for producing an offset signal on the output. The differential mode filter includes an input, an output, and active circuitry for sensing a differential mode signal and producing variations in resistance between the input and output to offset the differential signal.
