Abstract
Disclosed is a sampling circuit for a receiver in a wireless communication device that eliminates the need for separate discrete filtering components that can be expensive and bulky. The system utilizes techniques for ensuring that system components do not become saturated by blocker signals as a result of the removal of the discrete filter. Further, active filters are used in place of the discrete filter only when a blocker signal is present to minimize power consumption. In addition, the dynamic range of a sampling circuit can be altered in the presence of a blocker signal to ensure that the baseband signal is adequately detected.
