摘要： An integrated circuit (IC) is provided with a plurality of diode based mm-wave peak voltage detectors (PVD)s. During a testing phase, a multi-point low frequency calibration test is performed on one or more of the PVDs to determine and store a set of alternating current (AC) coefficients. During operation of the IC, a current-voltage sweep is performed on a selected one of the PVDs to determine a process and temperature direct current (DC) coefficient. A peak voltage produced by the PVD in response to a high frequency radio frequency (RF) signal is measured to produce a first measured voltage. An approximate power of the RF signal is calculated by adjusting the first measured voltage using the DC coefficient and the AC coefficient.

摘要： A device includes an output circuit that includes an input port at which a signal is received, an output port at which an impedance-adjusted representation of the signal is provided, and a set of bond wires connecting the input and output ports. The device further includes first and second couplers, each including a respective coupling bond wire along the set of bond wires for inductive coupling with the set of bond wires. The first coupler is oriented relative to the distributed-element output circuit to measure forward power provided by the impedance-adjusted representation of the signal via the output port. The second coupler is oriented relative to the output circuit to measure reflected power received via the output port.

摘要： A method of detecting a relatively weak signal includes providing an oscillatory loop that can sustain oscillations, wherein the oscillatory loop has no more than one or an even-number of stages. The loop includes a first weakly bistable differential amplifier and a second weakly bistable differential amplifier. At least one of the first and second weakly bistable differential amplifiers is connected to a behavior perturbing coupling which is operative to introduce into the connected-to amplifier a behavior tipping signal where, even if the behavior tipping signal is much weaker than an oscillation of the one or multistage oscillatory loop, the relatively weak behavior tipping signal can nonetheless alter the oscillatory behavior of the multistage oscillatory loop in a distinguishable way. The system may be used for detecting outside a patient's body weak manifestations of internal nerve firings.

摘要： A bi-directional bridge includes a forward bridge portion, and reverse bridge portion and a shared portion that enables the simultaneous measurement of power flowing in both directions while reducing insertion losses, providing better impedance matching and/or providing improved directionality. In some embodiments, additional attenuation is provided to reduce the common mode rejection requirements of detectors used with the bridge. In other embodiments, multi-tap attenuators and steering circuits may be integrated into the forward and/or reverse bridge portions to reduce common mode signal levels while still maintaining high levels of sensitivity for measuring small input signals.

摘要： An on-chip power sensor and a millimeter-wave communication device (e.g. transmitter or transceiver) on a chip including the on-chip power sensor are described. The millimeter-wave communication device can also include a coupler disposed on a transmit path, the coupler being configured to receive a transmit signal and to provide the transmit signal to an antenna connection (e.g. pad). The on-chip power sensor can be configured to receive a coupled portion of the transmit signal from the coupler, and measure a transmit power of the transmit signal based on the coupled portion of the transmit signal.

摘要： Provided is a partial discharge detection device for a transformer, and a transformer using the same. An on-load tap changer is provided on one side of the outer casing of a transformer, and is partitioned from the inside of the outer casing by a shielding wall. A drain pipe is formed on one side of the outer surface of the outer casing. A drain valve is installed in the drain pipe. A configuration for detecting a partial discharge signal generated within the transformer is installed in the drain pipe. That is, a detector body is installed within the drain pipe and the drain valve. A connection mounting member is installed in an end portion of the drain valve. The detector body penetrates the connection mounting member. In the meantime, a portion, such as the on-load tap changer, is partitioned from the internal space of the outer casing by the shielding wall.
