Counting Chain Asynchronous Pulse Counters TRIZ Cases
- Fractional Frequency Divider With 0.5-Step Clock Division
A counter, delay circuit, and multiplexer enable 0.5-step clock division while maintaining 50% duty cycle and suppressing subharmonics.
- Writable D Flip-Flop Counter Layout for High-Speed Image ADC
Cascaded writable D flip-flops simplify image-sensor ADC counting, enabling CDS, lower power, smaller layout, and stable ADAF in HDR readout.
- DC Motor Ripple Count Circuit for Sensorless Speed and Position
By filtering armature current ripple, this case derives DC motor speed and rotor position without Hall sensors or magnetic rings.
- Strong-Arm Frequency Divider for Low-Power Differential Clocks
A strong-arm latch divides a single-phase clock into accurate differential half-frequency outputs while cutting power and easing timing alignment.
- Ripple Count Circuit for DC Motor Speed and Position Sensing
By filtering armature current ripple, this circuit derives DC motor speed and rotor position without Hall sensors or magnetic rings.
- N-Bit Counter Reload Logic for Glitch-Resistant Frequency Division
Grouped-bit reload logic lets an N-bit counter restart cleanly under clock glitches, reducing metastability and output frequency deviation.
- Counter-Timer Array for Autonomous Peripheral Signal Patterns
Programmable counter-timer units generate complex peripheral pulse patterns without per-transition CPU control, cutting load and power use.
- Phased Clock Pulse-Width Correction for SERDES Jitter
Digital sampling of unit-interval clock pulse widths detects phased clock error and adjusts delay paths to reduce SERDES jitter.
- Adaptive Frequency Divider Circuit for Low-Noise 10 GHz Clocks
Sub-sampling feedback adjusts divider delay to cut phase noise and power in 10 GHz clock division without extra resampling latches.
- Asynchronous Programmable Divider With Segmented Divisor Control
Segmenting divisor bits lets an asynchronous divider sustain higher clock frequency and lower power by adding LSBs only on selected cycles.
