Abstract: The present application provides a packaged gate drive circuit having a transformer. The transformer which is used to transfer both signals and power from a primary side to a secondary side. The windings of the transformer are formed using a combination of tracks and wirebond wires. The transformer is positioned in a well formed using a first insulating material and covered with a second insulating material.

Abstract: A method and a digital circuit for synthesizing an input signal to produce an output signal are provided. The circuit includes a delay unit with a delay input and a delay output, a switch, and a controller. The selectively switch routes the input signal to the delay input whereafter the switch routes the delay output to the delay input. The controller controls the delay unit in response to the input signal and the output signal. A counter is provided to count a predetermined number of times the delay output is routed to the delay input whereafter the input signal is routed to the delay input to trigger the delay input. The digital circuit synthesizes the input signal to define a Delay-Locked loop (DLL) in which the delay unit is a voltage controlled delay line (VCDL). The invention extends to a computer program product executing the method and to an embedded circuit including the digital circuit.

Abstract: A transformer (1) for a printed circuit board (2) is provided with physically separate flat metal windings (6) which are chosen to take the highest or the two highest currents handled by the transformer (1). The lower currents which will often include the power input to the primary are printed on the surfaces (3,4) of the printed circuit board (2). The flat metal windings (5) may be pre-assembled with the core halves (6,7).
