Discontinuous Tuning TRIZ Cases
- Switchable Winding Inductor Topology for Multi-Band LC Resonators
Selective series winding paths widen LC resonator frequency coverage while saving chip area and limiting insertion loss in transceivers.
- VCO Tuning Bank Switching for High-Q Frequency Adjustment
Level-shifted switching across capacitor tuning banks lets an integrated VCO adjust frequency while preserving high Q-factor and lower noise.
- Capacitor-Switched Oscillation Circuit for Low-Power Radio Tuning
Discrete capacitor switching linearizes oscillator frequency control for manual radio tuning while cutting receiver cost and power use.
- Variable Capacitance Oscillator Control for Fine Temperature Compensation
Time-division switching between capacitance settings improves oscillator temperature compensation without smaller capacitor elements.
- RF Transmitter Circuit for Short Antenna Bandwidth Tuning
Gate-controlled series resistance lets a short-antenna RF transmitter widen bandwidth temporarily while protecting switches from high voltage.
- Multi-Mode Inverted-F Antenna Tuning for Hand Detuning
Adjustable coupling on both sides of the antenna feed lets a compact housing antenna retune for left-hand, right-hand, or free-space use.
- Process Corner Analog Current Control for Lower IC Power Dissipation
Process corner detection lets fast-corner ICs scale down analog current, cutting overall power dissipation, heat, and battery drain.
- Radio Tuning Circuit for Mute-Free Frequency Adjustment
Separate oscillation and tuning capacitor control lets AM radios change frequency without muting output or adding switching noise.
- RF Transmitter Circuit for Short-Antenna Bandwidth Switching
A capacitor-coupled switching circuit changes short-antenna Q and bandwidth while shielding RF switches from damaging high voltage.
- Tunable Wideband Distribution Circuit for Multi-Band Impedance Matching
A programmable gain buffer and tunable line impedance improve wireless power transfer across multiple frequency bands.
- Universal LNB Switching Linear and Circular Polarity Signals
A universal low noise block receiver switches between linear and circular polarity formats via integrated switching means.
- Remote Programmable Reference for Flexible Calibration
Software-configurable parameters replace dedicated hardware to resolve complexity and deployment time bottlenecks.
- Trimmable Wire LC Tank Frequency Adjustment
Trimmable wires adjust LC tank frequency without parasitic resistance, preserving the Q factor and minimizing layout area.
