Audio Amplifier TRIZ Cases
- Class-D Amplifier Tri-Wave Scaling for Linearity at Voltage Switching
Tri-wave level scaling with changing operating voltages keeps class-D output duty ratio stable, cutting quiescent current without losing linearity.
- Resistive DAC Force-Sense Routing for Low Distortion Output
Separate force and sense paths cut parasitic impedance distortion in resistive DACs while reference compensation improves output accuracy.
- Resistive DAC Summing Junction Routing for Low-Distortion Output
Separate force and sense paths plus impedance-compensated reference routing reduce parasitic distortion in HDR and EHDR resistive DACs.
