    Abstract: An electronic system comprising a voltage-to-current converter and a proportional-to-absolute-temperature (PTAT) circuit is disclosed. The voltage-to-current converter is configured to receive one of a control voltage, a supply voltage, a scaled-down version of the control voltage, and a scaled-down version of the supply voltage, and generate a set of currents. The PTAT circuit is coupled with the voltage-to-current converter such that each current of the set of currents is one of sourced to the PTAT circuit and sank from the PTAT circuit. Further, the PTAT circuit is configured to receive at least one of the supply voltage and the control voltage, and generate a set of reference voltages. The control voltage is generated based on the set of reference voltages and the supply voltage.

    Abstract: A radar device including a radar function, a driver configured to control a pass device, and a radar controller. The radar function is configured for generating radar frames in a first mode for generating high isolation frames and in a second mode for generating low isolation frames. The radar function has a supply voltage input and is configured to operate with the supply voltage input at a radar supply voltage level. The radar controller configures the driver for controlling the pass device to regulate voltage provided to the supply voltage input of the radar function at the radar supply voltage level with high power supply rejection ratio to minimize ripple voltage when the radar function is in the first mode, and configures the driver to force the pass device into a bypass mode to reduce power dissipation when the radar function is in the second mode.
