Abstract
A signal-receiving and signal-processing unit connected to one or several conductors is configured to transmit information-carrying signals in the form of voltage pulses. The conductor is connected to a transistor in a signal-receiving circuit to affect a current by using variations in the voltage pulses and the voltage value of a pulse. The current is in the form of pulses that pass through the transistor. The current is generated by the voltage pulse variations and voltage level. The current is given a signal-adapted information-carrying form by a signal-processing circuit. The transistor in the signal-receiving circuit is coordinated with at least one other transistor so that together they form a current mirror circuit.
Claims70
A signal receiving and processing unit connected to at least one conductor for transmitting information carrying signals as voltage pulses comprising:
- a signal receiving circuit including a first transistor, directly connected to the conductor, for affecting a current according to variations in the voltage pulses and a voltage value of a voltage pulse, wherein the current is in a form of pulses that pass through the transistor and is generated by the voltage pulse variations and voltage level;
- a signal processing circuit for processing the affected current according to a signal information carrying form;
- and
- a floating current mirror circuit including at least a second transistor coordinated with the first transistor.
