Potentiometer implements Logarithmic Gain Control: 10/23/97 EDN-Design Ideas / (Circuit / schematic design added 6/06)
-- Trimmer potentiometers are ubiquitous components and are available in a variety of packages, Resolutions, and temperature stabilities but
none of these potentiometers implements anything but the usual linear function of resistance vs. shaft position as useful in many audio
applications |

Log amp uses capacitor charging law: 01/10/02 EDN Design
Ideas / (added 1/05) The novel logarithmic amplifier in Figure 1 relies on the exponential charging characteristics of a
simple RC circuit. The expression for the time, T, required for a capacitor, C, to reach a voltage (VIN-VK) from 0V, when charged through a
resistor, R, with an applied voltage of VIN, is VIN-VK=VIN (1-e-T/RC), where VK is a fixed voltage. ... |
