Line Impedence Variation Compensation TRIZ Cases
- Diplexed Broadband Power Amplifier for Low Intermodulation
Separating broadband signals into low and high bands enables efficient amplification with lower intermodulation and better linearity.
- Multi-Protocol Ethernet Line Driver Without Internal Termination
A unified current-mode line driver supports 100Base-T and 10Base-Te while cutting area and power through termination-free impedance matching.
- Mixed-Mode Repeater Circuit for Fast Standby Signal Wake-Up
A mixed-mode repeater uses tri-state isolation and switch logic to cut standby power while enabling fast low-frequency signal transmission.
- Low-Voltage Line Driver Using Current-Mirror Output Decoupling
A current-mirror output stage decouples transconductance from differential nodes, enabling 1.8 V line driving with lower power.
- Adaptive Receiver Termination Calibration for Impedance Matching
Digital calibration feedback adjusts receiver termination resistance to match transmitter impedance and prevent signal reception errors.
- Calibration Circuit Reset Switching for Stable Impedance Matching
By resetting impedance-adjusting transistors before each code change, this circuit suppresses switching noise and keeps comparator-based matching stable.
- Variable Impedance Matching Using a Single Digital Feedback Loop
A single digital feedback loop with mixed recursive and non-recursive filters cuts impedance-matching circuit complexity and cost.
- Segmented SST Transmitter Slices for Orthogonal Zcal and FFE
Independent slice-level Zcal and tap assignment let a segmented SST transmitter tune impedance and FFE separately without losing matching range.
- Filterless Double-Conversion Receiver Circuits for Dual-Carrier Reception
Double-conversion receiver circuits use phase-shifted mixers to enable concurrent dual-carrier reception without intermediate-frequency filtering.
- Transmission Mode Configurator for Copper Wire Networks
A transmission mode configurator selects SISO or MIMO modes based on detected line characteristics to optimize internet service delivery.
- Bus System Circuit for Impedance Stabilization
A bus circuit measures connection resistance to dynamically set termination values.
- Bimodal Impedance Terminator for Data Bus Signal Integrity
A bimodal impedance terminator couples resistors and a capacitor to the differential signal lines of a data bus.
- Ringing Suppression Circuit for CAN Bus Impedance Control
A suppression circuit lowers bus impedance during dominant to recessive transitions to mitigate signal reflections.
