LOW PHASE NOISE, HIGH Q, HIGH GAIN AMPLIFIER IN AN INTEGRATED CIRCUIT

摘要

An amplitude feedback control loop to control the output power level of an amplifier. The amplifier is analyzed as a classical feedback control system. Some important additions to the amplitude and frequency feedback control are required to realize a practical form of the invention on an integrated circuit. In its most general sense, the input signal is the input referred thermal noise of the amplifier plus any external source of energy. In its realization as a source the external signal is not required.
