Abstract: The disclosure relates to technology for shifting a frequency range of a signal. In one aspect, a circuit comprises a frequency mixer, a frequency synthesizer configured to generate an oscillator signal, a programmable driver, and a controller. The programmable driver is configured to receive the oscillator signal from the frequency synthesizer and to provide the oscillator signal to the oscillator input of the frequency mixer. The programmable driver is configured to have a variable drive strength. The controller is configured to control the drive strength of the programmable driver based on a frequency of the oscillator signal to adjust a rise time and a fall time of the oscillator signal at the oscillator input of the frequency mixer.

Abstract: The disclosure relates to technology for generating multi-phase signals. An apparatus includes 2{circumflex over ( )}n phase signal generation stages. The apparatus also includes a controller configured to provide a mode input of each of the 2{circumflex over ( )}n stages with an active periodic binary signal with remaining inputs of each of the 2{circumflex over ( )}n stages provided with another periodic binary signal to collectively generate a 2{circumflex over ( )}n phase signal in a first mode. The controller is further configured to provide the mode input of each of 2{circumflex over ( )}(n−1) odd stages with a first steady state signal and the mode input of each of 2{circumflex over ( )}(n−1) even stages with a second steady state signal with remaining inputs of each of the 2{circumflex over ( )}n stages provided with the same periodic binary signal as in the first mode to cause either the 2{circumflex over ( )}(n−1) odd stages or the 2{circumflex over ( )}(n−1) even stages to collectively generate a 2{circumflex over ( )}(n−1) phase signal in a second mode.

Abstract: A device includes a temperature-variable voltage controller, in which the temperature-variable voltage controller comprises: a voltage regulator; a process monitor circuit coupled to the voltage regulator, in which the process monitor circuit includes a ring oscillator, and a frequency counter coupled to an output of the ring oscillator; and a temperature-variable current source coupled to the voltage regulator so that, during operation, the output voltage of the voltage regulator is compensated based on a change in temperature of the temperature-variable current source.
