Japan, Feb. 24 -- MASSACHUSETTS INSTITUTE OF TECHNOLOGY has got intellectual property rights for 'GENERATION AND SYNCHRONIZATION OF PULSE WIDTH MODULATION (PWM) WAVE FORM FOR RADIO FREQUENCY (RF) USE.' Other related details are as follows:
Application Number: JP,2024-134838
Category (FI): H03K3/017,H03H7/38@B
Stage: SOLUTION: To disclose a pulse width modulation (PWM) generation device having a phase shift element and a wave form combiner, in which the phase shift element contains: a pair of IQ modulators that is constructed so as to receive a reference signal synchronized by the PWM wave form; a digital-analog converter (DAC) that includes first and second outputs coupled to an I/Q input of one IQ modulator of the pair of IQ modulators, and third and fourth outputs and inputs that are coupled to the I/Q input of the other IQ modulator of the pair of IQ modulators; and a micro controller that is coupled to the reference signal by controlling the DAC so as to control a phase shift of a signal IQ1 and a signal IQ2 of each output of the pair of IQ modulators. A wave form combiner includes: a first input coupled to the output of the one of IQ modulator; and a second input coupled to the output of the other IQ modulator.SELECTED DRAWING: Figure 33 (Grant)
