20080231759 | REMOVING INTERFERING SIGNALS IN A BROADBAND RADIO FREQUENCY RECEIVER - Various embodiments are directed to removing interfering signals in a broadband radio frequency (RF) receiver by implementing a silicon tuner arranged to replicate high quality factor (Q) performance without the advantages of using high Q components available for module tuners. In one or more embodiments, tuned filter elements within a broadband silicon tuner are reused to maximize the attenuation of unwanted signals while minimizing induced undesirable channel ripple. In various implementations, a number of tuned passive inductor/capacitor filter elements are combined as required such that filter elements for an unused frequency band are reconfigured to provide attenuation of and enhanced immunity to unwanted signals. Other embodiments are described and claimed. | 09-25-2008 |
20090085660 | AGC MODULE AND METHOD FOR CONTROLLING NOISE FIGURE AND INTERMODULATION CHARACTERISTICS THEREIN - An Automatic Gain Control (AGC) module for controlling Noise Figure (NF) and IM characteristics therein is disclosed. The AGC module comprises a plurality of AGC stages. Each AGC stage comprises a differential amplifier circuit, an input signal transistor and a current-steering circuit. Differential amplifier circuits of the plurality of AGC stages receive control signals at their differential inputs and their output is connected to a common load. The input signal transistors of the plurality of AGC stages receive a common input signal and is further coupled to the differential amplifier circuit and the current-steering circuit. The current-steering circuits and the control signals at the differential amplifier circuits control gain of the each AGC stage of the plurality of AGC stage, which is used to control the NF and the IM characteristics. | 04-02-2009 |
20150042295 | DUAL MODE VOLTAGE REGULATOR WITH RECONFIGURATION CAPABILITY - A dual mode voltage regulator according to one embodiment includes a passive regulator circuit, a switching regulator circuit, and a controller circuit configured to determine parameters of an external select input. The controller is configured to selectively couple, on a cold boot up, either the passive regulator circuit or the switching regulator circuit between an input voltage port and an output load based on the determination of parameters. | 02-12-2015 |
