A Transformerless Ground Loop Isolating Preamplifier-Introducing Current Balanced Circuit Technology

Document Thumbnail

Current Balanced- technology is described with a circuit that achieves extraordinary isolation and CMRR characteristics without a transformer. The circuit is DC coupled, connects to unbalanced equipment, and provides signal gain without compromising CMRR. Like a transformer, it implements two-port audio signal isolation that is characterized by a balance in the currents flowing in and out of each port.
