Apparatuses, systems, and methods for, and more particularly to apparatuses, systems, and methods for a high-speed composite amplifier driving circuit to generate and output analog signals. The high-speed composite amplifier driving circuit can combine a voltage-controlled pulser and waveform generator with high-accuracy current-voltage (I-V) measurement functions. The voltage-controlled pulser and waveform generator, for example, can provide a 5 volt, 10 milliamp waveform at up to 50 megahertz with 5 nanosecond rise/fall timing and 8 ns minimum pulse widths. In addition, the high-accuracy I-V measurements can measure a 10 volts, 10 milliamp waveform at up to 30 MHz with 7-10 nanosecond rise/fall timing and 8 to 12 nanosecond minimum pulse widths.
