Manufacturer:ST Description:Note: It is natural to assume that with the addition of the averaging capacitor, the LOG AV output would become the average of the log of the absolute value of IIN. However, since the capacitor forces an ac ground at the emitter of the output transistor, the capacitor charging currents are proportional to the antilog of the voltage at the base of the output transistor. Since the base voltage of the output transistor is the log of the absolute value of IIN, the log and antilog terms cancel, so the capacitor becomes a linear integrator with a charging current directly proportional to the absolute value of the input current. This effectively inverts the order of the averaging and logging functions. The signal at the output therefore is the log of the average of the absolute value of IIN. |
