To address the challenge of improving power-added efficiency (PAE) for high-powered amplifiers, Analog Devices developed the ADL5511 TruPwr rms and envelope detector. The chip combines two RF ...

Here’s a crude (but simple to implement) complex signal envelope detection scheme. By envelope detection, we mean estimating the instantaneous magnitude of a complex signal x c (n). Whether this ...

In this letter to the editor, the author comments on Larry Langford’s recent article “Try This With Your AM Processing.” Comment on this or any article. Email [email protected]. Distortion in AM ...

There are two groups of classic circuits: those which have served us well in the past, but have been superseded by better designs, and those which are still in use, perhaps with updated components. In ...

Designers often choose a super-regenerative receiver—despite its frequency instability and poor selectivity—for battery-powered, short-range, wireless applications in which power consumption is a ...
