Abstract: A semiconductor test chip has an array of active semiconductor devices to be individually tested, a number of test lines for connection to external test circuitry, an enabling circuit associated with each device for selectively connecting it to the test lines, an input for receiving an instruction identifying a device that it is desired to test, and a decoder incorporated into the chip for receiving the instruction from the input. The decoder is connected by enabling lines to the individual test devices so that on receipt of an instruction the decoder enables the identified test device such that it becomes connected to the test lines. This circuit is more efficient and less cumbersome than the prior art.

Abstract: An electronic device includes a transmitter with a baseband input for a baseband signal, a mixer downstream from the baseband input, and a phase-locked loop (PLL) having a voltage controlled oscillator (VCO) and a phase detector coupled thereto, the VCO coupled to the mixer. A power amplifier is downstream from the mixer, and generates at least one aggressing signal that would otherwise generate an output pull of the VCO, causing transmit distortion on a transmit signal. A receiver is coupled to the power amplifier and has a sense input configured to receive the transmit signal. A VCO pulling compensation circuit is coupled to the baseband input and is configured to compensate the at least one baseband signal for the transmit distortion based upon the sensed transmit signal.

Abstract: A digital linear transmitter for digital to analog conversion of a radio frequency signal. The transmitter includes a delta sigma (ΔΣ) digital to analog converter (DAC) and a weighted signal digital to analog converter in the transmit path of a wireless device to reduce reliance on relatively large analog components. The ΔΣ DAC converts the lowest significant bits of the oversampled signal while the weighted signal digital to analog converter converts the highest significant bits of the oversampled signal. The transmitter core includes components for providing an oversampled modulated digital signal which is then subjected to first order filtering of the oversampled signal prior to generating a corresponding analog signal. The apparatus and method reduces analog components and increases digital components in transmitter core architecture of wireless RF devices.
