An electronic circuit for generating a delayed radio signal for use in a radio communication device configured to provide a transmit baseband signal in a baseband, to up-convert the transmit baseband signal into a transmit radio signal in a radio band, to transmit the transmit radio signal in the radio band, and to simultaneously receive a receive radio signal in the same radio band, is provided. The electronic circuit may include a delay circuit configured to delay a copy of the transmit baseband signal by an amount of time to generate a delayed baseband signal, an up-converting circuit configured to shift the frequency spectrum of the delayed baseband signal to the radio band to generate a delayed radio signal, and an output circuit configured to output the delayed radio signal for a cancellation circuit to cancel the delayed radio signal from the receive radio signal.

Embodiments include a resistor, coupled on a signal path, that includes one or more resistive memory elements, such as one or more magnetic tunnel junctions (MTJs). The resistance of the resistive memory elements may be digitally trimmable to adjust a resistance of the resistor on the signal path. The resistor may be incorporated into an analog or mixed signal circuit to pass an analog signal on the signal path. Other embodiments may be described and claimed.

In general, in one aspect, the disclosure describes an apparatus that includes an inductive capacitive voltage controlled oscillator (LC VCO) to generate an output clock. A voltage to current converter is used to receive a forwarded clock and to inject the forwarded clock to the LC VCO. The output clock is a deskewed version of the forwarded clock.
