    Abstract: The present invention provides a driving circuit (100) in particular for driving a laser diode (700) or a modulator, at data speed in the order of Gb/s. The driving circuit (10) has a low-­voltage, high-speed output stage capable of driving efficiently a laser diode (700) or a modulator. The driver circuit (10) comprises a chain of circuits, said chain comprising a slew-rate control circuit, at least one translinear amplifier (200, 201, 202), a push/pull stage (300), and an output stage (400) for driving the load current. Due to its versatility, the driver can be used in other applications e.g. line drivers, cable drivers, high-speed serial interfaces for back-plane interconnect, etc. The driver can work at low supply voltages, e.g. 3.3V nominal down to 2.7V, with high power efficiency. One major clue is to use entirely the large signal current produced by the output stage, e.g. in the driven laser diode, without wasting current in supply lines.

    Abstract: The present invention relates to a polar modulation apparatus and method, in which a polar-modulated signal is generated based on separately processed phase modulation (PM) and amplitude modulation (AM) components of an input signal. An amplified polar modulated output signal is generated in accordance with the phase modulation and amplitude modulation components by using a differential power amplifier circuitry(30) and supplying an amplified phase modulation component to a differential input of the differential power amplifier circuitry(30). A bias input of the differential power amplifier circuitry(30) is controlled based on the amplitude modulation component, so as to modulate a common-mode current of the differential power amplifier circuitry(30). Thereby, a new concept of a polar modulator with static DC-DC converter and power and/or efficiency and/or linearity controlled output power amplifier can be achieved.

    Abstract: The present invention relates to a differential oscillator circuit and a method of controlling the frequency of an oscillator signal. An enhanced frequency tuning mechanism is provided for controlling the frequency of the oscillator signal. The frequency tuning mechanism comprises first frequency control circuitry for controlling the threshold voltage of respective load transistors (M3, M4) of the differential oscillator circuit, and second frequency control circuitry for controlling at least one of a common-mode current (I BIAS ) flowing through branches of said differential oscillator circuit, a tail current (I TUNE ) of an additional feedback circuit (M5, M6) cross-coupled between the drains of a differential transistor stage (Ml, M2) of said differential oscillator and respective gates of said load transistors (M3, M4), and a voltage applied at a middle point of a tapped coil of a resonating circuit of the differential oscillator circuit. Thereby, a linear fine tuning characteristic can be obtained, where the tuning mechanism may for example work as a "gear-box" by stepping coarsely with the first frequency control circuitry through fine intervals generated by the second frequency control circuitry.
