CMOS Advanced Galvanic Isolators for medical Electronics

PublishTime：2022-04-25

Safety standards for ac line-powered medical electronic systems require galvanic isolation to protect patients and operators from electrically-induced trauma. The direct connection between machine and patient together with the presence of conductive body fluids and gels increase the risk of injury; thus isolators used in these systems must be robust and reliable.
Optocouplers and transformers are commonly used within medical system isolation circuits, and their deficiencies well known to the design community. Optocouplers are notoriously slow and exhibit wide performance variations over temperature and device age. They are single-ended devices, and consequently, exhibit poor common mode transient immunity (CMTI). In addition, optocouplers are fabricated in Gallium Arsenide (GaAs) processes, with intrinsic wear out mechanisms that cause permanent reductions in LED emission at elevated temperature and/or LED current. This degradation reduces optocoupler reliability, performance and service life. While transformers offer higher speed and better reliability than optocouplers, they cannot pass dc and low-frequency signals, thereby imposing limits on system timing (e.g. ON-time and duty cycle). Transformers also tend to be large and power-inefficient, and often require additional external components for core reset.
