Abstract
An amplifier exploits Miller-effect capacitance in a cascaded multi-stage self-limiting amplifier arrangement to achieve automatic adaptive bandwidth behavior (without the use of an active feedback control loop). The Miller-effect capacitance varies in accordance with the amplifier signal-level, with the capacitance in turn varying the amplifier bandwidth. Bandwidth is decreased for low-signal-levels and increased for relatively high-signal-levels. The adaptive amplifier technique is especially useful to reduce broadband noise in an IF stage of a communications device before the usable signal is fed to a detector stage.
