Abstract: The present technology relates to a semiconductor chip that can ensure a low impedance current path in an I/O ring while suppressing attenuation of radio frequency signals. The semiconductor chip includes an I/O ring surrounding a core circuit, first and second pads serving as input/output terminals for radio frequency signals, and a radio frequency signal transmission line electrically connected to the first and second pads and the core circuit. The radio frequency signal transmission line is formed above the I/O ring. The present technology is applicable to a semiconductor chip that performs input and output of RF signals.

Abstract: The present technology relates to a modulator and a modulation method for enabling provision of a highly convenient modulator. The modulator is configured to be input a first signal corresponding to one of a positive signal and a negative signal constituting a baseband signal of a differential signal, and a second signal having the same level as the first signal in one of an H level section in which the one signal is at an H level and an L level section in which the one signal is at an L level, and configured to generate a modulation signal obtained by modulating a carrier with the first and second signals to generate a modulation signal that is the amplitude shift keying (ASK)-modulated carrier with the baseband signal. The present technology can be applied to a case of modulating a carrier according to a baseband signal, for example.
