摘要： Described is an improved differential amplifier arrangement with a temperature compensated feedback circuit (12) which sets and stabilizes the DC bias point of the amplifier (10). The circuit averages the two outputs of the amplifier and generates a DC voltage (24) which is compared with a reference voltage (26) to generate a control signal which is amplified (16) and is used to control

摘要： The invention relates to an improved electrical amplifier (22) including a circuit arrangement which biases the amplifier (22) so that current in an output stage of the amplifier (22) is constant even though its load current varies. The circuit arrangement is configured so that the biasing current in the output stage is varied dynamically, thus compensating for changes in the current of the load (18) which the amplifier (22) drives.

摘要： A high current CMOS driver device including a raised cosine signal generator for generating a raised cosine signal waveform and an input circuit arrangement (26) for controlling the raised cosine signal generator is described. The raised cosine signal generator includes an output node (V OUT ) to which a controlled chain of CMOS inverters are connected. The input circuit arrangement accepts an input signal (V IN ), converts it into appropriate signals which drive respective inverters (10,10′) so that simultaneous conduction of inverter pairs is prevented. This device minimizes ground bounce, electrical noise and radiation problems caused by large current transients or spikes (di/dt) that usually accompany such circuits.
