A log amplifier, also known as logarithmic amplifier or logarithm amplifier or log amp, is an amplifier for which the output voltage Vout is K times the natural log of the input voltage Vin. This can be expressed as, $${\displaystyle V_{\text{out}}=K\ln \left({\frac {V_{\text{in}}}{V_{\text{ref}}}}\right)}$$where … Zobacz więcej Log amplifiers are used in many ways, such as: • To perform mathematical operations like multiplication, division and exponentiation. Multiplication is also sometimes called mixing. This is … Zobacz więcej The reverse saturation current for the diode doubles for every ten degree Celsius rise in temperature. Similarly the emitter saturation current varies significantly from one transistor … Zobacz więcej • Diode • Operational amplifier applications § Logarithmic output Zobacz więcej The relationship between the input voltage $${\displaystyle V_{\text{in}}}$$ and the output voltage $${\displaystyle V_{\text{out}}}$$ is given by: Zobacz więcej • Integrated DC logarithmic amplifiers from Maxim's AN 36211 • Analog electronics with Op Amps by A. J. Peyton, V. Walsh Zobacz więcej WitrynaA logarithmic amplifier, or a log amplifier, is an electronic circuit that produces an output that is proportional to the logarithm of the applied input. This section …

WitrynaLogarithmic amplifiers utilize the logarithmic relationship between V BE and collector current in transistors. This characteristic is very temperature sensitive and requires … WitrynaAn operational amplifier in which the output voltage of the amplifier (V0) is directly proportional to the natural logarithm of the input voltage (Vi) is known as a logarithmic amplifier. Basically, the natural logarithm of the input voltage is multiplied by a constant value and produced as output. Log Amplifier Circuit hertz car hire murcia airport
