Abstract: A dual quartz crystal microbalance (QCM) sensor is disclosed for use in a hand-held detection device (10) for detecting the presence of an odorant in hydrocarbon gaseous fuels. The odorant is a thiol-based compound, such as ethanethiol. One QCM (16) is coated with a coating typically containing a reagent that specifically reacts with the thiol of the odorant and alters its oscillation frequency as a result of mass gained in the reaction. A second QCM (16?) serves as a control and the two frequency signals may be heterodyned (26) to produce a delta-frequency representative of the mass change. Circuitry and signal processing (32) are used to produce a final result correlated to the level of thiol in the hydrocarbon gas.

Abstract: A multi-mode power management circuit is provided. The multi-mode power management circuit includes a second generation (2G) amplifier circuit(s) configured to amplify a 2G radio frequency (RF) signal for transmission in a 2G RF band(s). The multi-mode power management circuit includes a pair of tracker circuitries coupled to the 2G amplifier circuit. Each tracker circuitry includes a charge pump circuitry configured to generate a voltage and a current. When the 2G amplifier circuit amplifies the 2G RF signal for transmission in the 2G RF band(s), both charge pump circuitries are controlled to provide two currents to the 2G amplifier circuit. As a result, the 2G amplifier circuit is able to amplify the 2G RF signal to a higher power corresponding to a sum of the two currents for transmission in the 2G RF band(s).
