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: 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.
