摘要： An electronic circuit comprises: an input terminal; an output terminal; first and second supply rails; first, second, third, and fourth field effect transistors, FETs, each of a first type and each having respective gate, source and drain terminals; and first and second loads. The source of the first FET is connected to the first supply rail, the drain of the first FET and the source of the second FET are connected to the output terminal, the drain of the second FET is connected to the second supply rail, the gate of the third FET and the gate of the fourth FET are connected to the input terminal, the drain of the third FET is connected to the second supply rail, the first load is connected between the first supply rail and the source of the third FET, and the second load is connected between the drain of the fourth FET and the second supply rail. In one aspect of the invention, the gate of the first FET is connected to a node between the source of the third FET and the first load such that a voltage at the source of the third FET is applied to the gate of the first FET, and the gate of the second FET is connected to a node between the drain of the fourth FET and the second load such that a voltage at the drain of the fourth FET is applied to the gate of the second FET.

摘要： An antenna comprises: a first terminal; a second terminal; and a winding, having an inductance, comprising a plurality of turns and connected between the first and second terminals such that a change in magnetic flux linking the winding generates a corresponding voltage between said terminals. The winding comprises a conductive element connected to the first and second terminals and extending around said turns from the first terminal to the second terminal and having a thickness not exceeding Xμm along a length of the conductive element from the first to the second terminal and a width not exceeding Xμm along said length, where X is less than or equal to 10, whereby said conductive element is substantially non-visible to a naked human eye.
