CL includes probe and test-fixture capacitance. B. Phase relationships between waveforms were chosen arbitrarily. All input pulses are supplied by generators having the following characteristics: PRR ≤ 1 MHz, ZO = 50 Ω, tr = 6 ns, tf = 6 ns. C. The outputs are measured one at a time with one input transition per measurement. D. tPLH and tPHL are the same as tpd. Figure 1. Load Circuit and Voltage Waveforms |
