摘要: According to one exemplary embodiment, a circuit arrangement includes power amplifier configured receive an RF input signal. The further control and convert the signal output DC voltage. voltage coupled peak detector circuit, where outputs analog bias coupling of amplifier. causes have quiescent current that increases in way is substantially logarithmic with respect amplitude An increase can cause linear voltage, measured dBm.
