Abstract
A signal communication circuit and methods for using the same are disclosed. In one embodiment, a circuit for signal communication includes a signal line configured to transmit signals, a transmitter circuit configured to drive a transmitted signal onto the signal line, a receiver circuit configured to detect the transmitted signal based on a deviation of a received signal from a reference signal on the signal line, and the receiver circuit is further configured to use the received signal to communicate the transmitted signal.
Claims24
A circuit for signal communication, comprising:
- a signal line configured to transmit signals;
- a transmitter circuit configured to drive a transmitted signal onto the signal line;
- a receiver circuit configured to detect the transmitted signal based on a deviation of a received signal from a reference signal on the signal line, wherein the deviation of the received signal from the reference signal on the signal line is a controlled voltage transition having a magnitude proportional to a ratio of capacitance between a capacitor of the transmitter circuit and capacitors of the signal line;
- and
- the receiver circuit is further configured to use the received signal to communicate the transmitted signal.
A method of signal communication, comprising:
- driving, by a transmitter circuit, a transmitted signal onto a signal line;
- detecting, by a receiver circuit, the transmitted signal based on a deviation of a received signal from a reference signal on the signal line, wherein the deviation of the received signal from the reference signal on the signal line is a controlled voltage transition having a magnitude proportional to a ratio of capacitance between a capacitor of the transmitter circuit and capacitors of the signal line;
- and
- using, by the receiver circuit, the received signal to communicate the transmitted signal.
The circuit of method 13, wherein the signal line is configured to transmit bi-directional signals for different periods of signal transmission.
