Abstract: A built-in receiver self-test system provides on-chip testing with minimal change to the receiver footprint. The system digitally generates a two-tone test signal, and tests the nonlinearities of the receiver using the generated two-tone test signal. To that end, the self-test system comprises a stimulus generator, a downconverter, and a demodulator, all of which are disposed on a common receiver chip. The stimulus generator generates a test signal comprising first and second tones at respective first and second frequencies, where the first and second frequencies are spaced by an offset frequency, and where the first frequency comprises a non-integer multiple of the offset frequency. The downcoverter downconverts the test signal to generate an In-phase component and a Quadrature component. The demodulator measures an amplitude of the intermodulation tone by demodulating the In-phase and Quadrature components based on a reference frequency.

Abstract: A current-mode regulator relies on indirect current measurement to facilitate slope compensation used to stabilize the operation of a buck converter. The current-mode regulator comprises an inductor, a switching network, and a controller. The inductor delivers an output current to a load. The switching network selectively connects the inductor input to an input voltage or a second voltage. The regulator controls the switching network. An inner loop control circuit of the regulator comprises the switching network, a current measuring circuit, a slope circuit, a comparator, and a switching controller. The current measuring circuit comprises a passive network connected to the inductor input and operative to indicate an inductor current as a measurement voltage. The slope circuit applies a time-varying voltage having a positive slope to the measurement voltage. The comparator compares a slope compensated measurement voltage to the control voltage. The switching regulator controls the switching network in response to the output of the comparator.

Abstract: A method permits a UE receiver to detect and report to the network a scrambling code collision (i.e., two neighbor cells transmitting with the same scrambling code while timing is aligned). The UE receiver decodes the PCCPCH's physical channel with all the associated broadcast information while a scrambling code collision at the UE is present. The UE reports SFN-SFN information to the network, to insure the UE mobility and then prepare the handover to a new detected cell. This process and a respective apparatus are usable in the presence of MIMO and further improve the detection of the scrambling code collision in the presence of MIMO.
