Figure 50 and Figure 51 show the output signal swing and
frequency spectrum at 500 kHz. At this frequency, the output
signal (at VOUT), which has a peak-to-peak swing of 1.95 V
(50 mV to 2 V), has a THD of 68 dB (SFDR = 77 dB).

Figure 52 and Figure 53 show the output signal swing and
frequency spectrum at 2 MHz. As expected, there is some
degradation in signal quality at the higher frequency. When the
output signal has a peak-to-peak swing of 1.45 V (swinging
from 50 mV to 1.5 V), the THD is 55 dB (SFDR = 60 dB).
This circuit could also be used to drive the analog input of a
single-supply, high speed ADC whose input voltage range is
referenced to ground (for example, 0 V to 2 V or 0 V to 4 V). In
this case, a back termination resistor is not necessary (assuming
a short physical distance from transistor to ADC); therefore, the
emitter of the external transistor would be connected directly to
the ADC input. The available output voltage swing of the circuit
would therefore be doubled.
