Overdrive Recovery
Overdrive of an amplifier occurs when the output and/or input
range are exceeded. The amplifier must recover from this over-
drive condition. As shown in Figure 36, the AD8051/AD8052/
AD8054 recovers within 60ns from negative overdrive and
within 45ns from positive overdrive.

Driving Capacitive Loads
Consider the AD8051/AD8052 in a closed-loop gain of +1 with
+V
S
= 5 V and a load of 2 k
in parallel with 50 pF. Figures 37
and 38 show its frequency and time domain responses, respec-
tively, to a small-signal excitation. The capacitive load drive of
the AD8051/AD8052/AD8054 can be increased by adding a
low valued resistor in series with the load. Figures 39 and 40
show the effect of a series resistor on capacitive drive for varying
voltage gains. As the closed-loop gain is increased, the larger
phase margin allows for larger capacitive loads with less peak-
ing. Adding a series resistor with lower closed-loop gains ac-
complishes the same effect. For large capacitive loads, the
frequency response of the amplifier will be dominated by the
roll-off of the series resistor and the load capacitance.

Circuit Description
The AD8051/AD8052/AD8054 is fabricated on Analog Devices’
proprietary eXtra-Fast Complementary Bipolar (XFCB) pro-
cess, which enables the construction of PNP and NPN transis-
tors with similar f
T
s in the 2 GHz–4 GHz region. The process is
dielectrically isolated to eliminate the parasitic and latch-up
