Connect a DC ammeter to the V
CC
pin and measure. The
ammeter is shorted for use in subsequent measurements.
Input a 1.0V
P-P
, 100kHz sine wave to SG, and obtain G
V
from the following formula given TP1 voltage as V1
and TP3 voltage as V2.
G
V
=20LOG (V2/V1) dB
For the above G
V
measurement, given TP3 voltage for
10MHz as V3, F
C
is obtained from the following
formula.
F
C
=20LOG (V3/V2) dB
Input a 1.0V
P-P
staircase wave to SG, and measure
differential gain at TP3.
APL=10~90%
Proceed as for DG, and measure differential phase.
Measure the DC voltage difference of each switch
status at TP2.
Assume VC1=2.1V, VC2=0.7V.
Input a 2.0V
P-P,
4.43MHz sine wave to SG, and given
TP1 voltage as V4 and TP3 voltage as V5, C
T
is
obtained from the following formula.
