    摘要： A modulated Class E transmitter is disclosed. In one embodiment of the invention, the modulated Class E oscillator achieves high coil currents (˜1A) and voltages (˜500V) with low power components by precisely timed injection of current when the oscillating current in the inductor passes through zero. A detector circuit is used to trigger the current injection at the appropriate instant regardless of changes in the resonant frequency of the system. Its phase can be adjusted to compensate for propagation delays in the drive circuitry, while amplitude modulation is accomplished by switching in additional reactive conductance to increase the current injected into the tank circuit.

    摘要： A CIRCUIT FOR PERFORMING AMPLITUDE MODULATION OF A CARRIER SIGNAL BY A MODULATING SIGNAL. THE CARRIER AND MODULATING SIGNAL ARE FIRST SUMMED AND THEN APPLIED TO THE INPUT OF THE MODULATOR CIRCUIT WHICH IS COMPRISED OF A PLURALITY OF BRANCH CIRCUITS, EACH HAVING UNIDIRECTIONAL IMPEDANCE ELEMENTS WHICH ARE SELECTIVELY RENDERED CONDUCTIVE IN ACCORDANCE WITH THE INSTANTANEOUS VALUE OF THE INPUT SIGNAL APPLIED TO THE MODULATOR FOR DEVELOPING CURRENT SIGNAL AT THE OUTPUT OF THE MODULATOR WHICH IS A PREDETERMINED FUNCTION OF THE INSTANTANEOUS VALUE OF THE SIGNAL, THE CURVE OF SAID FUNCTION BEING DETERMINED BY THE RESPECTIVE ADMITTANCE VALUES OF THE IMPEDANCE ELEMENTS EMPLOYED IN THE MODULATOR CIRCUIT. FIRST AND SECOND MODULATOR CIRCUITS MAY BE COMBINED IN A SINGLE CIRCUIT TO PROVIDE FOR AMPLITUDE MODULATION AND CARRIER WAVE SUPPRESSION, OR ALTERNATIVELY, FOUR SUCH MODULATOR CIRCUITS MAY BE USED IN COMBINATION TO PROVIDE A HIGH QUALITY ELECTRONIC RESOLVER CIRCUIT FOR SYNTHESIZING ORTHOGONALLY MODULATED VECTORS.

    摘要： An integrated circuit comprises a dual port modulator and a voltage controlled oscillator (VCO). The dual port modulator has a first input for receiving a transmitter modulation signal, a first output for providing a fractional portion of a high port modulation signal, a second output for providing a integer portion of the high port modulation signal, and a third output for providing a low port modulation signal. The VCO is coupled to the dual port modulator and has a first input for receiving the fractional portion of the high port modulation signal, a second input for receiving the integer portion of the high port modulation signal, a third input for receiving a tuning signal based on the low port modulation signal, and a first output for outputting an RF signal. The dual port modulator provides a signed single bit signal for generating the fractional portion of the high port modulation signal.
