Abstract: The invention provides a system and method of generating a number of inputs to the mixer elements in a direct conversion (homodyne) receiver configuration using Virtual Local Oscillator (VLO) techniques. These generated inputs meet the requirement that they must have a fixed and stable phase-relationship, as well as being correctly related in terms of their power spectra relative to the operating radio (RF), intermediate (IF), and baseband frequencies of the system, and that when applied to the mixer elements they permit the mixer elements to create internally the effect of applying the Local Oscillator signal at a suitable frequency.

Abstract: A method of measuring changes in signal level output of an integrated circuit sensor by providing a direct current (DC) or low frequency (AC) bias to the sensor and placing a floating gate semiconductor device on-chip and coupling the floating gate of the semiconductor device with the sensor. As a result, changes in signal level output of the sensor modulate charge at the gate. The semiconductor device in turn converts the modulated charge at the gate into output signals proportional to the changes in the signal level output. The measurement method provides a resolution in the sub-atto range.

Abstract: An RF direct down-conversion topology that is insensitive to leakage and device mismatching is presented. According to the system the RF signal is split into two arms with each arm having a mixer. Each mixer has two inputs namely a phase modulated local oscillator signal and the RF information signal. The phase modulated local oscillator signal between each arm differs by a 90 degrees phase shift. The output of the mixers is subtracted and the output of the subtractor is mixed with the phase modulation signal. The output of the third mixer represents the base band. A low pass filter then removes the unwanted signals.

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.
