摘要
A fast-settling line driver circuit capable of high-speed operation. The line driver is particularly well-suited for operation in a high-resolution imaging system. The line driver circuit comprises a signal amplifier that is configured in a negative feedback loop and connected to a bus line through a switch network. The switch network is disposed inside the feedback loop while the line driver is transmitting a signal onto the bus line. This configuration reduces the settling time of the line driver by substantially eliminating the effect of the switch resistance on the RC time constant. The line driver also comprises offset cancellation and presettle circuits that improve the integrity of the output signal and reduce the power consumption of the system.
