Amplitude-Modulated Carrier Systems TRIZ Cases
- Rotary Joint RF Link Using Polarization for Full-Duplex Data
Mm-wave RF with elliptically polarized antennas and a diplexer keeps rotary joints in continuous full-duplex data transfer despite rotation and contamination.
- Coupled Transmission-Line Interconnect for Wirebond Bandwidth Limits
A coupled transmission-line network offsets wirebond inductance to push interconnect bandwidth beyond 50 GHz for 100 Gbps modulation.
- 2.4G TPMS Wake-Up Circuit Without Low-Frequency Antennas
A 2.4G TPMS wake-up scheme replaces low-frequency antennas and circuits, cutting antenna count, signal burden, and installation complexity.
- Delta Detector Control for Smooth Audio Level Adaptation
By comparing signal averages across time intervals, this case adapts attack and release times to keep audio levels smooth with low latency.
- OFDM Trigger Timing Bias Correction for Multipath Synchronization
Bias-corrected correlation helps OFDM receivers pick accurate symbol timing in multipath channels, reducing ISI without training sequences.
- BP Equalization via QR Decomposition for Massive MIMO Detection
By splitting complex signals into real and imaginary parts before QR decomposition, this case cuts BP equalization overhead in Massive MIMO.
- Isolation IC Carrier Frequency Gating for Lower Idle Power
By stopping carrier output during input disabling periods with timing pulses, this isolation IC cuts unnecessary modulation power use.
- Carrier Frequency Control in Isolation ICs for Lower Power Modulation
Timing-pulse carrier control stops unnecessary oscillation during input disabling periods, cutting modulation circuit power use.
- Capacitive Isolated Link Using Frequency Mixing for High CMTI
Dual-frequency modulation, mixing, and envelope detection improve common-mode transient rejection in capacitive isolated data links.
- Capacitive Isolated Differential Link for Common-Mode Transient Rejection
Dual-frequency modulation and mixer-based detection let a capacitive isolated differential link reject common-mode transients despite capacitor mismatch.
- Waveform Amplitude Encoding for Noise-Resistant Data Compression
Amplitude drops and baseline modulation add data to each wave or pulse, improving compression while resisting attenuation and noise.
- Terahertz Wave Multi-Level Modulation for Faster Data Transmission
Multi-level voltage modulation in the oscillation region raises terahertz data rate beyond binary amplitude schemes while keeping transmission stable.
- Coherent Optical Channel Labeling With PN Codes for Polarization Swaps
PN alignment codes label quadrature polarization channels so coherent receivers can detect phase rotation and channel swaps with low ambiguity.
- Broadband Signal Source Using Parallel Harmonic Signal Paths
Multiple phase-shifted, amplified harmonic paths are combined to widen bandwidth and raise center frequency without relying on a single high-frequency IC path.
