Figure 16. Gain and Phase Characteristics vs. Frequency
(0 kHz–10 kHz)
Figure 16 shows a more limited frequency range with enhanced
accuracy. T he figures are transfer functions with the input to be
considered as a sinusoidally varying mechanical position and the
output as the voltage from the AD698; the units of the transfer
function are volts per inch. T he value of C2, C3, and C4, from
Figure 7, are all equal and designated as a parameter in the fig-
ures. T he response is approximately that of two real poles.
However, there is appreciable excess phase at higher frequen-
cies. An additional pole of filtering can be introduced with a
shunt capacitor across R2, Figure 7; this will also increase phase
lag.
When selecting values of C2, C3 and C4 to set the bandwidth of
the system, a trade-off is involved. T here is ripple on the “dc”
position output voltage, and the magnitude is determined by the
filter capacitors. Generally, smaller capacitors will give higher
system bandwidth and larger ripple. Figures 17 and 18 show the
magnitude of ripple as a function of C2, C3 and C4, again all
equal in value. Note also a shunt capacitor across R2, Figure 7,
is shown as a parameter. T he value of R2 used was 81 k
with a
Schaevitz E100 LVDT .
