    摘要: A feedback and shift unit is arranged to reduce to a minimum the number of processing steps required in a processor, such as a DSP, to achieve a particular operating function, such as a linear feedback shift or a stepping function used by encryption algorithms. The feedback and shift unit (50) comprises a linear feedback shift register (52) for storing a value of the feedback and shift unit. A tap register (56) stores a tap position indicator indicative of tap positions for the feedback and shift unit (50). An input provides data to the feedback and shift unit. A feedback matrix, coupled to receive the data from the input, provides data bits, generated in response to the data and the tap position indicator, that are shifted into the linear feedback shift register (52) to form the value stored therein.

    摘要: A power supply for an electric appliance having an operating mode and a standby mode includes a transformer block (9) for producing a constant power output into two low voltage outputs (Vc and Vcc), an operating power supply circuit (2) coupled to one of the two low voltage outputs (Vcc) to power the appliance during the operating mode, and a receiver circuit (3) coupled to the other low voltage output via an impedance path (14, 15). The receiver circuit (3) includes a switch (17) for switching a very low impedance into a path parallel with the first impedance when it receives a signal indicating that the appliance is to enter the standby mode, so that the voltage at the other low voltage output (Vcc) is reduced, thereby increasing the current drawn by the receiver circuit (3) and thus reducing the power available to the operating power supply circuit (2).

    摘要: A switched capacitor differential circuit switches first and second differential input signals (Vinp1, Vinp2) to respective inputs (A, B) of an operational amplifier (12) via respective first and second signal paths. Each signal path includes a coupling capacitor (13, 14) and two switching devices (2, 3 and 4, 5) to switch the input signals to charge the capacitors at a first phase of a clock signal and to discharge the capacitors onto the inputs of the amplifier at a second phase of the clock signal. In order to remove common mode spikes from transferring to the amplifier, a pair of comon mode capacitors (16, 17) are coupled between the inputs and a common node (15), which is coupled via a pair of switches (6, 7) to the first and second signal paths between the capacitors and the second of the switching devices so that the coupling capacitors are discharged relative to the common node.

    摘要: A method of forming a package assembly (10) including a package (12) that encapsulates an electronic die. A leadframe (30) has edge rails (32), and the die is disposed on the leadframe. The package is formed around the die to encapsulate it, and the leadframe is trimmed to provide a plurality of leads (14) protruding from a first side of the package. This trimming also provides a support (16) connected to a second side of the package. The support is bent to be substantially orthogonal to the common plane containing the leads. A mounting tip (26) on the support is thus disposed outside of the common plane. This support improves the rigidity and natural bending frequency of the package assembly.

    摘要: A noise cancelling circuit (1) is used with a D/A converter , the converter including a first modulator (11) and a data output. The circuit (1) comprises an error measuring arrangement (12, 13, 14) for measuring a quantization error signal of the modulator (11). A filter (19) receives the error signal and provides a filtered error signal. A filter compensator (17) coupled to the data output provides a compensated output. A scaler (15) coupled to receive the filtered error signal provides a scaled filtered error signal. A second modulator (16) coupled to receive the scaled filtered error signal provides a single bit stream of error data. A summing arrangement (18) sums the single bit stream of error data and the compensated output from the first modulator and provides a corrected output, such that the error signal is filtered, scaled and modulated and the data output is compensated such that the corrected output is obtained having a substantially reduced quantization error.
