Abstract
Official abstract text for this publication.
A signal coupling circuit for generating an output signal according to an input signal is provided. The signal coupling circuit includes: a coupling capacitor, configured to generate a coupling signal according to the input signal; a clock generating circuit, configured to generate a clock and determine a duty cycle of the clock by the coupling capacitor; a discharge circuit, configured to intermittently discharge the coupling capacitor according to the duty cycle of the clock; and an output circuit, coupled to the coupling capacitor, for generating the output signal according to the coupling signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A signal coupling circuit, configured to generate an output signal according to an input signal, comprising: a coupling capacitor, configured to generate a coupling signal at an output terminal of the coupling capacitor according to the input signal that varies and is provided at an input terminal of the coupling capacitor; a clock generating circuit, configured to generate a clock, and to determine a duty cycle of the clock by the coupling capacitor; a…
