Latest Patents
Chan Shufan holds a patent for a "High speed digital bus termination." This invention discloses novel methods and apparatuses for terminating busses based on the number of devices secured to the bus. The impedance of the bus lines varies with the number of devices coupled to the bus. The invention determines the number of devices coupled to the bus line and selects a precision resistor based on this number to match the expected impedance of the bus. A voltage is generated across the precision resistor with a known current, which is then compared with the voltage generated across controllable resistances, such as a FET biased in the linear mode. A feedback network provides a control voltage to the control electrode of the FET, ensuring that the resistance of the FET equals the selected precision resistance. This innovative approach allows for precise control of the bus termination, enhancing the performance of digital communication systems.
