Patent number: 8644427Abstract: A radio frequency receiver with dual band reception and dual analog-to-digital converters (ADCs) can be configured to operate in a single channel mode or a dual channel mode to receive a single RF input channel or two RF input channels at the same or different frequency bands. In the single channel mode, the dual ADCs can be used to improve the performance of the receiver for the single input signal or the dual ADCs can be configured for reduced power consumption. In the dual channel mode, the dual ADCs operate on the individual RF input signals to realize dual band reception. In one embodiment, the receiver is configured for asymmetric dual band reception to receive a wideband input signal on a first input signal path and a narrow band input signal on a second input signal path.Type: GrantFiled: August 10, 2011Date of Patent: February 4, 2014Assignee: SiGear Europe SarlInventors: Alain-Serge Porret, Friederich Mombers, Melly Thierry

Patent number: 8576951Abstract: A mixed-signal radio frequency receiver implements multiple spur avoidance modes to reduce or remove spurs or digital noise injection into the received channel to enhance the receiver performance. The multiple spur avoidance modes are reconfigurable to allow a single mode or multiple modes to be selected for use depending on the application. One or more spur avoidance modes can be selected to enhance the performance of the receiver or the modes can be selected to reduce power consumption. The same spur avoidance circuit is used to support all of the spur avoidance modes by reconfiguring the circuit for each mode or each combination of modes. In another embodiment, a clock masking scheme is applied to align analog and digital clock edges to separate digital activities from sensitive analog activities.Type: GrantFiled: October 24, 2011Date of Patent: November 5, 2013Assignee: SiGear Europe SarlInventors: Friederich Mombers, Alain-Serge Porret, Melly Thierry
