摘要： Methods and apparatus are described for reducing or eliminating break-before-make, i.e. dead time distortion, in switching amplifiers. A switching amplifier (M1, M2) has an input stage (510) for generating a switching signal. Break-before-make distortion compensation circuitry (504) alters the switching signal. Break-before-make generator circuitry (506) generates two drive signals from the altered switching signal. A power stage includes two switches (D1, D2) which are alternately driven by the two drive signals. Break-before-make distortion detection circuitry (502) detects a distortion pattern at the power stage output node and controls the break-before-make distortion compensation circuitry (504) to alter the switching signal in response to the distortion pattern detected to thereby eliminate at least some break-before-make distortion.

摘要： In a digital-analog hybrid LSI including an analog circuit (2) and a digital circuit (3), the analog circuit (2) includes a circuit for sampling, according to the operation timing of a switch (4), information to be processed by the analog circuit (2) in a capacitor (5). A clock signal generating means (6) generates an operation reference clock signal (b) for the digital circuit (3) so that the change of the clock signal (b) is stopped at a timing when the switch (4) is opened, i.e., during a specified period (T) which includes the high-to-low transition timing of the clock signal. This prevents the analog characteristic of the analog circuit (3) from being degraded by digital noise that is transferred through the junction capacitance of the semiconductor chip (1).

摘要： A device and method for sigma-delta modulation may include an input signal and a plurality of integrators. The output of the integrators and a data input may be input to an adder, the sum output to be input to a quantizer to generate a quantized output signal. A reset input to the first integrator may be asserted during a first sample of the quantized output signal to reduce the signal discontinuity at the input of the first integrator, which improves the stability of the sigma-delta modulator.

摘要： Embodiments of the invention include an oversampling Analog to Digital Converter that uses uneven non-overlapping clock phases to reduce switched capacitor circuit power consumption. A return-to-zero sub phase of one of the clock phases may also be used for feedback reference capacitors. A delay lock loop may be combined with the non-overlapping clock phase generator to control accurate timing.

摘要： A data processor is disclosed. The data processor includes a data processing module. The data processing modules includes an input for receiving an input signal, an output for providing a quantized output signal, a combining unit configured to combine a feedback signal from the output with the input signal and a quantizer configured to provide the quantized output signal based on the combined signal. The data processor further includes a correction module configured to receive the quantized output signal, generate a full-scale digital signal based on the quantized output signal, determine a metastability error in the full-scale digital signal and provide a compensated output signal based on the quantized output signal and the determined metastability error.

摘要： A delta-sigma Analog-to-Digital Converter (ADC) (IC) which includes an input feed-forward path extending from an input to the ADC to a feed-forward summing circuit disposed between a loop filter and quantizer of the ADC, and a filter disposed in the feed-forward path as an apparatus for improving distortion performance in the delta-sigma ADC. The filter may be a low pass filter, for example, a Resistor-Capacitor (RC) circuit. The filter may have a cut-off frequency outside the ADC's passband. The filtering provided may be continuous-time filtering, even if the delta-sigma ADC is a discrete-time delta-sigma ADC.
