Abstract
A high-speed/high-slew-rate tri-modal all bipolar buffer/switch includes a unity-gain amplifier, a voltage source, and a maximum level detector and a minimum level detector adjusting a current source to sink or source current as required to quickly make the output voltage of the switch equal to the input voltage of the switch. The maximum level detector and the minimum level detector compare the output voltage to the input voltage. If the output voltage does not equal the input voltage, the current source acts as either a sink or source to make the output voltage equal the input voltage. In addition, the voltage switch holds a constant d.c. voltage at the output of the switch when the switch is powered down.
