PRECISION POSITIVE PEAK DETECTOR
In Figure 32, CH must be polystyrene, Teflon, or polyethylene
to minimize dielectric absorption and leakage. The droop rate is
determined by the size of CH and the bias current of the AD820.
PRECISION THRESHOLD DETECTOR/AMPLIFIER
In Figure 33, when VIN < VTH, amplifier output swings negative,
reverse biasing diode D1. VOUT = VTH if RL = ∞. When VIN
VTH, the loop closes.
