Active Element Network TRIZ Cases
- Tunable Duplexer Using Dielectric Position Control Across Sub-Bands
A movable dielectric tuner shifts filter frequency across sub-bands, expanding duplexer use while reducing spare-part inventory.
- Resistive Directional Coupler Circuit for Low-Frequency Chip Integration
Using resistive and amplifier circuits instead of inductors, this coupler stays compact at low frequencies and fits semiconductor chips.
- High-Order Damping Circuit for Stable Multi-Stage Amplifiers
A nested Miller compensation scheme with high-order damping shifts non-dominant poles higher while preserving in-band gain and stability.
