Delta Modulation TRIZ Cases
- RF Sigma-Delta Modulator Feedback Gain Compensation for Higher SNDR
Adjustable feedback-path gain offsets mixer delay and oscillator-drive deviations in an RF Sigma-Delta modulator to improve SNDR.
- Adaptive Dynamic Range Control for Sigma-Delta Audio Noise
Adaptive gain scaling cuts quantization noise and audio artifacts in sigma-delta outputs while lowering power use at reduced oversampling ratios.
- Power Transmission Sampling Module With Optical Isolation
Optical isolation after ADC conversion cuts transformer bulk, cross-talk, and sampling skew in power transmission signal acquisition.
