摘要： A drive circuit for driving the transmitter windings of an inductive position transducer includes an oscillating power source. A resonator section is connected to the power source. The resonator section includes an impedance transforming section, a transmitter winding of the inductive position transducer, and feedback loops which cause the power source to oscillate at the resonator frequency. The resonator operating frequency and the load impedance imposed on the power source by the resonator can be independently selected. In various exemplary configurations of the drive circuit, the resonator operating frequency adapts to variations in the impedance of the transmitter windings. The drive circuit is particularly well-suited for driving low-impedance and/or miniaturized inductive position transducers with enhanced efficiency and accuracy. In various exemplary configurations of the drive circuit, the peak operating voltage of the transmitter windings can exceed the power supply voltage.

摘要： To prevent an undesired operating mode of voltage-controlled oscillation (VCO) circuitry from dominating a desired operating mode (e.g., an in-phase operating mode or an out-of-phase operating mode), a supply reset and ramp pulse may be provided to the VCO circuitry when switching to a new mode, such that supply voltage to the VCO circuitry is reset (e.g., set to 0 V or another reference voltage), and gradually increased or ramped up back to a steady-state voltage (e.g., used to maintain a mode) within a time duration. Additionally or alternatively, a switch control bootstrap pulse may be provided to the VCO circuitry that is bootstrapped to (e.g., applied instantaneously or concurrently with) switching the VCO circuitry to the new mode. After a time duration, the VCO circuitry may switch back to a steady-state voltage (e.g., used to maintain the new mode).

摘要： A wireless system includes an active oscillator and a front-end circuit. The active oscillator is used to generate and output a reference clock. The active oscillator includes at least one active component, and does not include an electromechanical resonator. The front-end circuit is used to process a transmit (TX) signal or a receive (RX) signal according to a local oscillator (LO) signal. The LO signal is derived from the reference clock.

摘要： An electronic apparatus for testing an integrated circuit (IC) that includes a ring oscillator is provided. The apparatus configures the ring oscillator to produce oscillation at a first frequency and configures the ring oscillator to produce oscillation at a second frequency. The apparatus then compares the second frequency with an integer multiple of the first frequency to determine a resistive voltage drop between a voltage applied to the IC and a local voltage at the ring oscillator. The ring oscillator has a chain of inverting elements forming a long ring and a short ring. The ring oscillator also has an oscillation selection circuit that is configured to disable the short ring so that the ring oscillator produces a fundamental oscillation based on signal propagation through the long ring and enable the short ring so that the ring oscillator produces a harmonic oscillation based on a signal propagation through the short ring and the long ring.
