Delivering a Signal to a Load

Posted September 14, 2016 12:00 AM by Engineering360 eNewsletter

To transmit data from a source to a load, make sure nothing gets lost or distorted along the way. The circuit to do that job is a driver. This article surveys the problems that can arise and the different types of driver circuits that are designed to handle them. The driver must provide adequate voltage and current for the receiving device. If the data is transmitted over a cable, the driver has to overcome the cable's impedance, which becomes an important factor either for high frequency analog signals or fast rise-time digital pulses — and it must have a fast enough response time.
