This paper demonstrates a high frequency power detector with high conversion gain for frequency-shift sensing applications used in biosensing systems. The proposed design comprises an amplitude-to-voltage convertor (AVC), a peak detector, and a bandgap. To increase the operating frequency range, AVC utilizes half of an RMS power detector to attain the power measure of an input signal. Since the input...
This paper introduces a high frequency power detector with high conversion gain for frequency-shift applications. The proposed design comprises an amplitude-to-voltage converter (AVC), a peak detector, and a bandgap. To increase the operating frequency range, AVC utilizes the half of an RMS power detector to attain the power measure of an input signal. Since the input power is converted to a DC voltage...
