Latest Patents

Richard J Blumberg holds a patent for a "Receiver circuit with a bus-keeper feature." This invention discloses a bidirectional input/output buffer where the receiver includes complementary bus keeper transistors. The keeper transistors are of opposite conductivity types and have their gates coupled to the output of a receiver inverter. This design reinforces the driven data state at the input of the receiver in a CMOS latch fashion. It also holds the prior data state after the driving output driver is in tristate. The keeper transistors possess significantly weaker drive characteristics than the other receiver transistors, allowing them to be easily overdriven with the next data state if different. Additionally, the source/drain resistance of the keeper transistors is quite high, resulting in relatively low power dissipation during switching. These characteristics are achieved by providing relatively long channel lengths for the keeper transistors compared to other transistors in the circuit.
