Abstract
A RF digital to analog converter has a first capacitor arrangement, a first common node, and a first controller. The first capacitor arrangement has multiple switchable capacitor paths arranged in parallel. Respective switchable capacitor paths have a switchable element and a capacitor coupled in series. The first common node is connected to the multiple switchable capacitor paths. The first controller receives a baseband signal having a component, and a local oscillator (LO) signal. The first controller combines the component and the LO signal to obtain a first modulation signal. The first controller controls the multiple switchable capacitor paths of the first capacitor arrangement with the first modulation signal.
