摘要： An isolation device for isolating a first signal of a first circuit from a second circuit disclosed. The isolation device may have a substrate and a plurality of metal layers disposed on the substrate. The plurality of metal layers have a topmost metal layer disposed furthest away from the substrate and a first interconnect metal layer formed nearest to the substrate. The first interconnect metal layer is disposed at a first distance away from the substrate, whereas the topmost metal layer is disposed at an isolation distance away from a first adjacent metal layer formed nearest to the topmost metal layer. A portion of the topmost metal layer forms a first plate. The first plate is configured to transmit the first signal from the first circuit to a second plate that is connected to the second circuit, but electrically isolated from the first plate.

摘要： Various embodiments of systems for transmitting and receiving a plurality of signals across an isolation material are disclosed. In one embodiment, a first signal may be modulated into a first modulated signal. The first modulated signal is then modulated into a second modulated signal in accordance to a second signal using amplitude modulation. In another embodiment, a first signal and a second signal are modulated into a modulated signal before being modulated further using amplitude modulation. The detection of the modulated signal may be performed using a frequency detector and an amplitude detection circuit that are arranged in parallel. At least some of the apparatuses, circuits, systems and methods disclosed herein may be implemented using conventional CMOS design and manufacturing techniques to provide, for example, at least one or more integrated circuits.
