A Dynamic Controlled Output (DCO) circuit is designed in. During
the transition, it initially lowers the output impedance to effectively
drive the load and, subsequently, raises the impedance to reduce
noise. Figures 2 and 3 show V
illustrate the output impedance and drive capability of the circuit. At
the beginning of the signal transition, the DCO circuit provides a
maximum dynamic drive that is equivalent to a high drive standard
output device.
