Signal isolators using micro-transformers

摘要

A method for providing an isolated logic output signal, comprising: in response to receiving an input data signal, generating an edge detection signal indicating a rising or falling edge of the received input data signal; transforming the edge detection signal from a first voltage to a second voltage; inputting the transformed edge detection signal to a first input of a first logic circuit and to an input of a signal generator; outputting from the signal generator a logic signal to a second and third input of the first logic circuit, wherein the logic signal is representative of a duration of the edge detection signal; and in response to an output from the first logic signal, generating an isolated logic output signal.
