Abstract
A logarithmic detector amplifying (LDA) system is provided for use as a high sensitivity receive booster or replacement for a low noise amplifier in a receive chain of a communication device. The LDA system may include an amplifying circuit configured to receive an input signal having a first frequency and generate an oscillation based on the input signal, a sampling circuit coupled to the amplifying circuit and configured to terminate the oscillation based on a predetermined threshold to generate a series of modulated pulses, and one or more resonant circuits including at least one variable capacitor, coupled with the amplifying circuit and configured to establish a frequency of operation and generate an output signal having a second frequency being substantially the same as the first frequency, with the operating frequency being adjustable in response to baseband information received from the system via the one or more variable capacitors.
