Multiple Input And Output Pulse Circuits TRIZ Cases
- Programmable Brown-Out Reset Circuit for Power-Response Tradeoffs
A programmable BOR circuit shifts between low quiescent current and fast voltage-drop response to protect logic and extend battery life.
- Power-On Reset Circuit Topology to Prevent Through Current
Series PMOS control stabilizes the reset signal during internal voltage rise-up, preventing VDD-to-GND through current and failures.
- Optical Encoder Signal Conditioning for Stable Sinusoidal Amplitude
Peak-based feedback adjusts emitter current to keep encoder differential amplitude within range despite aging, drift, and contamination.
- Cascode Current Comparator for Low-Noise High-Speed Reception
Cascode current paths raise voltage swing and PSRR, improving noise immunity and reliable high-speed detection at low current levels.
- Current Conveyor Circuit for Fast, Stable Current Comparison
Dual current conveyors sum positive and negative transistor currents to compare larger currents accurately while stabilizing reference voltage.
- Dynamic Clock Edge Selection for Read Data Recovery
A master-slave interface adapts read sampling to delay variation by choosing the rising or falling clock edge for reliable data recovery.
- Current-Weighted Voltage Interpolation Buffer With Smaller Layout
Bias-current weighting replaces resistor voltage division to interpolate and buffer display drive voltages with less layout area and lower cost.
- Variable-Voltage Pulse Delay Circuit for Wide-Range Time Measurement
Adjustable drive voltage changes each delay stage to measure short and long time intervals in one compact circuit.
- Zero-Crossing Detector With Constant LED Current Isolation
A rectified-input current source keeps optocoupler LED current constant, cutting AC mains zero-crossing error to under 100 microseconds.
- Digital Amplifier PWM Synchronization for Delay and Noise Compensation
A feedback-controlled MPWM approach compensates time delay and power noise in digital amplifiers while preserving signal accuracy and efficiency.
- Common-Gate Ground-Sensing Comparator With Low-Offset Latch Path
A common-gate input stage, current-mirror amplifier, and SR latch enable ground-level sensing with low offset, wide bandwidth, and fast response.
- Zero-Crossing Sampled-Data Circuit for Precise Low-Noise Sampling
Level-crossing detection turns sampling switches off at zero crossing to capture output voltage precisely while reducing noise in switched-capacitor circuits.
- Serial Receiver Loss Detection With Threshold-Based Signal Gating
Threshold-based loss detection lets a serial receiver ignore weak or absent signals, cutting noise, power use, and PSRR-related issues.
