Signal receiving circuit and method, and signal detecting circuit

A system comprising:

• a signal receiving circuit configured to receive an input voltage signal, the input voltage signal including a first input pattern and a second input pattern, the signal receiving circuit including:
• an input voltage regulating circuit configured to modify a waveform shape of the input voltage signal to obtain a regulated voltage signal;
• and
• a comparing circuit configured to compare the regulated voltage signal with a reference voltage signal, the comparing circuit configured to generate a comparison voltage signal in response to the comparison,
• the comparison voltage signal having a first portion that corresponds to the first input pattern, and a second portion that corresponds to the second input pattern, the first portion defining a first pulse width, the second portion defining a second pulse width, the second pulse width being substantially the same as the first pulse width.

A method comprising:

• receiving an analog voltage signal, the analog voltage signal including a first input pattern and a second input pattern, the second input pattern being different than the first input pattern;
• modifying a waveform shape of the analog voltage signal to obtain a regulated voltage signal;
• comparing the regulated voltage signal with a reference voltage signal;
• and
• generating a comparison voltage signal in response to the comparison, the comparison voltage signal having a first portion that corresponds to the first input pattern, and a second portion that corresponds to the second input pattern, the first portion defining a first pulse width, the second portion defining a second pulse width, the second pulse width being substantially the same as the first pulse width.
