Transfer of digital data through a transformer

摘要

The method involves coding a digital data clock signal to be transferred for generating positive and negative amplitude pulses in respective directions at rising and falling edges of the signal to be transferred, respectively by complementary MOS inverters. The generated pulses are applied to a primary winding of a transformer (11), where primary current (Ip) in the primary winding (11p) is in a different direction based on the edges of the digital signal. The edges of an output signal are generated according to a direction of current (Is) in a secondary winding (11s) of the transformer. An independent claim is also included for a digital data clock signal transferring system comprising a digital signal coding circuit.
