Instrument (2) is thus a logarithmic amplifier with a sensitivity which can be adjusted by way of the bias.
This circuit includes a logarithmic amplifier (150) for receiving high frequency angular modulated signals and for providing a logarithmic amplifier output in response thereto.
The received signal is amplified by a logarithmic amplifier (408) so as to reduce the dynamic range of the signal.
A logarithmic amplifier gain stage for supplying, in response to an instantaneous input signal, an output signal corresponding to a logarithmic value of the input signal.
The electronics (12) may contain, for example, a source driver, a detector amplifier, a band-pass filter, a logarithmic amplifier and various voltage sources.
The control unit preferably comprises a log amplifier and a second ADC.
A programmable low noise, low distortion CMOS logarithmic attenuator/amplifier circuit is also disclosed.
The new addition to log amplifier outputs a signal whihc is linearly related to an input signal to the log amplifier.
The echo receiver of such device includes logarithmic preamplifier, programmable amplifier and a fast analog to digital converter.
A resulting signal current is amplified by a logarithmic amplifier and only the modulated frequency component is extracted by a DC reproducer.
The circuit also includes a logarithmic amplifier electrically connected to the equalizer and configured to generate a range of signals based on signals received at the antenna.
A logarithmic amplifier (11) having a large input range first detects the level of the baseband signal on the input side of a variable gain amplifier circuit (8).
The system can further include a logarithmic amplifier controller (122) in the feedback path coupled to the voltage controlled attenuator as well as a power amplifier (112) coupled to the voltage controlled attenuator.
