Figure 47. RMS Responding AGC Circuit with 100 dB Dynamic Range
100 dB RMS/AGC SYSTEM WITH MINIMAL GAIN
ERROR (PARALLEL GAIN WITH OFFSET)
Figure 47 shows an rms-responding AGC circuit that can be
used equally well as an accurate measurement system. It accepts
inputs of 10 μV to 1 V rms (100 dBV to 0 dBV) with generous
overrange. Figure 48 shows the logarithmic output, VLOG, which
is accurately scaled 1 V per decade, that is, 50 mV/dB, with an
intercept (VLOG = 0) at 3.16 mV rms (50 dBV). Gain offsets of
±2 dB were introduced between the amplifiers, provided by the
±62.5 mV introduced by R6 to R9. These offsets cancel a small
gain ripple that arises in the X-AMP from its finite interpolation
error, which has a period of 18 dB in the individual VCA
sections. The gain ripple of all three amplifier sections without
this offset (in which case, the gain errors simply add) is shown
in Figure 49; it is still a remarkably low ±0.25 dB over the
108 dB range from 6 μV to 1.5 V rms. However, with the gain
offsets connected, the gain linearity remains under ±0.1 dB over
the specified 100 dB range (see Figure 50).
