    Abstract: The present invention relates to an amplifier intended to deliver to a load impedance RL connected between two output terminals of the amplifier an output current Iout which is representative of an input signal (Vin, −Vin) applied to two input terminals of the amplifier, which amplifier includes a first and a second transistor T1 and T2 connected as a differential pair around the load impedance RL. The amplifier according to the invention further includes a third and a fourth transistor T3 and T4 which form a differential pair; degenerated by means of a degenerating impedance Req which has a nominal value equal to that of the load impedance RL of the amplifier, which differential pair (T3, T4) is intended to be controlled by means of a control signal (−Vin/2, Vin/2), in anti-phase with the input signal (Vin, −Vin). The invention permits to double the output current Iout of the amplifier without, however, increasing its power consumption.

    Abstract: A differential comparator with improved bit-error rate performance operating with a low supply voltage. The differential comparator includes a first pair of transistors receiving a differential input. A second pair of transistors is coupled to the first pair of transistors. A pair of resistive elements is connected between the first pair and second pair of transistors so as to increase bias currents shared by the first and second pairs of transistors. The increased bias currents reduce a time required by the differential comparator to transition from a meta-stable state to a stable state, thereby improving a bit-error rate of the differential comparator. The resistive elements can use linear resistors or transmission gates. Gates of either the first or second pair of transistors can provide an output.

    Abstract: A differential multiplexer includes a plurality of multiplexing circuits. Each multiplexing circuit inputs a corresponding differential input signal including a positive input signal and a negative input signal, and outputs positive and negative output signals. Each multiplexing circuit includes first, second, third and fourth transistors. The first and second transistors input the positive input signal. The third and fourth transistors input the negative input signal. Outputs of the first and third transistors are connected to the positive output signal. Outputs of the second and fourth transistors are connected to the negative output signal. The positive and negative output signals are controlled using gate voltages on the first and fourth transistors. The second and third transistors are turned off when the differential multiplexer is in use. The transistors are cross-coupled to make leakage between the positive and negative input signals common mode in the positive and negative output signals.

    Abstract: Clamping device (21) for clamping an optical disc on a turntable comprises a disc-pressure means (23), a support (5) for the disc-pressure means, which support is movable between an operating position and a rest position, and a permanent-magnet system comprising a first axially magnetized annular magnet (31) and a second axially magnetized magnet (29) secured to the support and to the disc-operating means respectively. In the operating position of the support the disc-pressure means is pressed against the disc on the turntable by magnetic force and the disc-pressure means is freely rotatable relative to the support. The permanent magnets are positioned coaxially relative to each other, a radial air gap (33) being formed between the first magnet (31) and the second magnet (29) in the operating position of the support.
