Patent number: 7969339Abstract: An integrated circuit comprises a delta-sigma modulator incorporating a delta-sigma modulation loop having an analog-to-digital converter in a forward path and a digital-to-analog converter in a feedback path such that the ADC is arranged to receive samples of an analog input signal. The ADC is operably coupled to auto-ranging logic arranged to shift a digital output signal from the ADC representative of the analog input signal to counteract an effect of an input variation of the analog input signal. In this manner, the application of auto-ranging logic with a self-recovery technique supports a reduction of the number of comparators required in a multi-bit delta-sigma ADC.Type: GrantFiled: March 23, 2006Date of Patent: June 28, 2011Assignee: Freescale Semiconductor, Inc.Inventors: Patrick Clement, Maher Kayal, Sergio Pesenti

Patent number: 7932844Abstract: In one embodiment, the present invention includes an integrated circuit comprising a radio frequency communication channel having a mixer and a programmable analog filter coupled to an output terminal of the mixer. The integrated circuit further comprises a digital-to-analog converter providing an AC signal to the digitally programmable analog filter, an analog-to-digital converter (ADC) coupled to an output terminal of the digitally programmable analog filter, and a digital calibration circuit that adjusts the filter frequency according to measurements calculated from the data from the ADC. During a first calibration phase, the filter frequency is adjusted to a first frequency and a first signal is measured. During a second calibration phase, the filter frequency is adjusted to a second frequency approximately equal to a frequency of the AC signal, and a second signal is measured. The filter frequency is further adjusted based on measured values of the first and second signals.Type: GrantFiled: August 17, 2009Date of Patent: April 26, 2011Assignee: Marvell International Ltd.Inventors: Thien Huynh, Philippe Mosch, Patrick Clement
