Abstract: A circuit arrangement for an LVDS driver, which uses combined bipolar and MOSFET technology with at least two MOSFETs, is shown, wherein a multiplier circuit is connected to an output stage of the LVDS driver and the multiplier circuit is controlled by means of an automatic control circuit, which generates control signals for controlling a current source of the multiplier circuit and for controlling the amplification factor of differential input signals of the multiplier circuit. Advantages of the invention are that it enables said technology, in which semi-conductor components are used in bipolar techniques (e.g. NPN and/or PNP transistors) (as well as MOS technology), to take advantage of the high speed of the bipolar elements compared with MOS elements.

Abstract: A logic level converter for translating differential CMOS logic signals to into differential logic signal pairs such as those associated with ECL levels. The converter includes two components. A first component consists of two branches coupled to the switchable CMOS level input and it provides a first switchable translated output. The second component is an ECL current switch. The current associated with the converter is mirrored through the branches to minimize the effects of fabrication, temperature, and/or power supply vagaries, as well as a very fast and tolerance independent signal level translation.
