Receivers for Improving Signal Integrity and Data-Rate in Controller Area Networks

Blog Article

This paper presents additional circuits and characterization methodologies of novel CAN (Controller Area Networks) receivers that implement new features, aiming at improving CAN signal integrity and data-rate.The first receiver shown includes a circuit for ringing iphone 13 pro max price florida removal.The use of a Notch filter is meant to remove the ringing.The pulse-width symmetry is improved to a range just lower than −20 ns and +15 ns.As a result, during arbitration, the transmission data-rate can be increased up to 8 Mbit/s, a higher limit must be evaluated on a network system level.

The second receiver shown is conceived for multi-bit communication.The possibility of parallelizing data transmission leads to an efficient use of the bandwidth available.A table compares the achieved results with the specifications of the latest available protocols.The chips of both receivers were designed and fabricated with a 0.18- $mu $ caruso milk thistle m BCD technology.

After a block level description of the receivers, a Direct Power Injection (DPI) methodology is described.It is used to evaluate the receiver’s immunity to conducted continuous-wave interference.Considerations regarding future technological directions for new applications are provided at the end of the paper.
