Amplitude Demodulation By Non-Linear Multiple-Pole Elements TRIZ Cases
- Active Transducer Bias Circuit for Leakage-Limited Neural Recording
AC coupling and a resistor-set bias path limit patient leakage current while preserving low-frequency electrophysiological signal recording.
- RF Squarer Circuit Feedback for Low-Power Signal Detection
An analog feedback path boosts low-power RF detection sensitivity while recovering DC offset and avoiding calibration or complex digital loops.
- RF Squarer Detector Feedback for Low-Power Signal Sensitivity
A feedback-driven reference transistor boosts low-power RF detection sensitivity while avoiding calibration and complex digital loops.
- Envelope Detection Circuit for Sub-THz CFO and Phase Noise
A local-oscillator-free envelope circuit shifts sub-THz signals to an intermediate band to cut CFO and phase noise impact.
