Electronic Switching TRIZ Cases
- I/O Keeper Cell Wake-Up Control for Low-Power State Retention
I/O keeper cells preserve configuration and data states through low-power exit, avoiding default resets that can disturb connected devices.
- I/O Keeper Cell Wake-Up Restore for Low-Power State Retention
Keeper cells preserve I/O configuration and data states through low-power wake-up, preventing default resets from disturbing connected devices.
- Current-Sensed Gate Driver Circuit for Lower Switching Loss
By sensing device current and varying mirror voltage, the gate driver boosts di/dt and dv/dt during large-current switching to reduce loss.
- Clock Switching Circuit With Synchronized Enable Gating
Synchronized enable and feedback gating suppress clock-switch glitches and avoid pulse-induced synchronization failure.
- Digital Output Buffer Slew Control Without RPO Resistors
A decoder-controlled PMOS/NMOS buffer limits noise spikes without RPO resistors, cutting fabrication cost and crossbar current.
- GaN Transistor Structure for Normally-Off Operation and High Drain Current
A p-type control layer injects holes to deplete polarization-induced carriers, enabling normally-off GaN operation with higher drain current.
- Thin-Film Transistor OFF-Current Reduction Using AC Drain Bias
Applying AC voltage at the TFT drain cuts OFF-current without extra pads or circuits, reducing static damage risk and process complexity.
- FPGA Shared Memory Interface Using Partial Reconfiguration
Using an FPGA configuration port as shared memory cuts co-simulation transfer overhead and speeds large data exchanges between design blocks.
- Multiplexer Output Delay Balancing for Uniform DDR Switching
A transistor chain delays fast multiplexer transitions to match slow ones, producing uniform DDR output timing with minimal circuit changes.
- State Machine Timing Control Against Clock Disturbances
An internal synchronized clock and adaptive evaluation timing protect state machines from clock disturbances, preventing bad outputs and crashes.
- Parallel IGBT Gate Coupling for Transient Current Equalization
Gate-coupled resistors and impedance circuits keep parallel IGBTs at equal gate-emitter voltage, limiting transient current imbalance and wear.
- IGBT Gate Driver Turn-Off Control for Surge Voltage and Losses
A delayed two-stage gate discharge limits collector surge voltage during IGBT turn-off while avoiding unnecessary switching losses.
- Differential Driver Circuit With Dynamic Edge-Steepness Trimming
Dynamic trimming equalizes differential signal edge steepness during operation to cut EMI and offset aging and temperature drift.
- Voltage Glitch Detection Circuit Using Reference Memory Comparison
Reference memory data is compared with sense-amplified output to detect voltage glitches and reset the CPU before IC card data is compromised.
- Touchscreen Gaming Character Responses for Player Engagement
Character images change by touch position and contact mode, turning passive game scenes into clearer, more engaging interaction.
- Detachable Wireless Keypad for Multi-Protocol Mobile Connectivity
A detachable keypad shifts wireless protocol support out of the base unit, enabling flexible network access with lower cost, weight, and power use.
