Analogue Adaptive Filters TRIZ Cases
- Adaptive Data Strobe Noise Suppression in LPDDR4 Receiver Circuits
Selective resistor coupling suppresses amplified LPDDR4 data strobe noise, preserving logic states when write data strobe is off.
- Differential Amplifier Resistor Switching for LPDDR4 Strobe Noise
Mode-controlled resistor switching suppresses LPDDR4 data strobe noise when WDQS is off, preventing logic errors and control circuit failures.
- Data Strobe Receiver Circuit With Adaptive Noise Suppression
Selective resistor coupling suppresses LPDDR4 data strobe noise when write DQS is off, preserving correct logic states in the control circuit.
- Reconfigurable Analog Filter With Variable Load Passband Control
A variable load circuit switches transimpedance amplifier impedance to balance wide passband tuning with sharp adjacent-channel rejection.
- Signal Processing Power Isolation for ADC Noise Immunity
A switched or filtered power rail with a reservoir capacitor blocks supply noise during critical ADC decisions to improve conversion accuracy.
- Serial AGC Filter Stages for Fast Gain Adaptation
One-shot backward AGC setting and switched-capacitance cells speed filter gain adaptation in wireless receivers despite settling limits.
- Piezoelectric Sensor Module Self-Powering Vibration Detection
A piezoelectric sensor module generates voltage from mechanical vibration resonance to power internal CMOS circuits without external energy sources.
- Signal Processing Noise Immunity via Power Switching
A signal processing apparatus uses a power supply switch to disconnect noise during critical operations.
