    Abstract: In accordance with an embodiment, a circuit includes a mixer having a signal input port, a local oscillator input port and an output port, a lowpass filter circuit having an input coupled to the output port of the mixer and a terminal configured to be connected to a shunt capacitor, and a difference circuit having a first input coupled to the output port of the mixer, and a second input coupled to an output of the lowpass filter. The output of the difference circuit substantially rejects a DC signal component at the output port of the mixer.

    Abstract: A voltage controlled oscillator arrangement is disclosed. The arrangement includes a voltage controlled oscillator and a bypass component. The voltage controlled oscillator has an output and a tuning port. The output provides an output signal at an operating frequency. The tuning port is configured to select the operating frequency according to an applied voltage. The voltage controlled oscillator has active portions and inactive portions. During the active portions, the output signal is at a non-zero value. The bypass component is configured to apply a bypass compensating signal to the tuning port during the active portions of the voltage controlled oscillator. The bypass compensating signal compensates for an oscillator temperature of the voltage controlled oscillator.

    Abstract: One embodiment of the present invention relates to a transmitter within a single integrated chip substrate, which is capable of continuous beam steering of a transmitted radar beam as well as an option to change the physical position of the origin of the transmit radar beam. The transmitter has a signal generator that generates an RF signal. The RF signal is provided to a plurality of independent transmission chains, which contain independently operated vector modulators configured to introduce an individual phase adjustment to the high frequency input signal to generate separate RF output signals. A control unit is configured to selectively activate a subset of (e.g., two or more) the independent transmission chains. By activating the subset of independent transmission chains to generate RF output signals with separate phases, a beam steering functionality is enabled. Furthermore, the subset defines a changeable position of the transmitted radar beam.

    Abstract: In accordance with an embodiment, a method includes receiving a first differential logic signal using a first branch of a circuit that extends from a voltage supply of the circuit as far as an earth terminal of the circuit and has at least one first differential transistor pair, receiving a second differential logic signal using a second branch of the circuit that extends from the voltage supply to the earth terminal and has at least one second differential transistor pair, conducting a current flow between the first branch and the second branch, and outputting an output signal by the second branch.
