Abstract: A digital-to-analog converter (DAC) includes: a plurality of first controllers and a plurality of resistor devices. The plurality of first controllers are configured to be selectively switched on according to a received digital signal to control an analog signal according to the received digital signal. The plurality of resistor devices are respectively connected to the plurality of first controllers. The plurality of resistor devices include non-volatile memory devices.

Abstract: Oscillators and methods of operating the oscillators are provided, the oscillators include an oscillating unit including at least one magnetic layer having a magnetization direction that varies according to at least one selected from the group consisting of an applied current, an applied voltage and an applied magnetic field. The oscillating unit is configured to generate an oscillation signal having a set frequency. The oscillators further include an output stage that provides an output signal by differentially amplifying the oscillation signal.
