SYSTEM AND METHODS FOR RAMP CONTROL
Abstract
A device including an input to receive a clock signal, a ramp start program register, a ramp start active register, a ramp stop program register, a ramp stop active register, a ramp slope program register, a ramp slope active register, an update controller, the update controller to update, based on a programmable condition, respectively, the ramp start active register contents, the ramp stop active register con- tents and the ramp slope active register contents, and a ramp controller to generate a ramp signal, the ramp signal to begin at the value reflective of the ramp start active register contents, the ramp signal to change value at each cycle of the clock signal based on the value reflective of the ramp slope active register contents, and the ramp signal to stop at the value reflective of the ramp stop active register contents. 23 Claims, 5 Drawing Sheets 100 y g MP 03 105 Vout

Patent Classification & AI Product Mapping
Authoritative patent classification definitions mapped to real-world technology domains and commercial product categories.
CPC H03K4/00
Confidence: High
Official Definition
Generating pulses having essentially a finite slope or stepped portions
ELECTRICITY > ELECTRONIC CIRCUITRY > PULSE TECHNIQUE
AI Technology & Product Mapping
Technology Domain:
Analog & Mixed-Signal Circuitry
Product Category:
Signal Generators & Timing Controllers
Plain-English Summary:
Circuits and methods for generating electrical signals that change gradually over time, such as ramps or staircases, rather than switching instantly.
Relation to Claims:
The patent discloses a ramp controller that generates a ramp signal using programmable registers for start, stop, and slope, aligning directly with generating pulses of finite slope.
CPC H03K4/06
Confidence: High
Official Definition

ELECTRICITY > ELECTRONIC CIRCUITRY > PULSE TECHNIQUE
AI Technology & Product Mapping
Technology Domain:
Analog & Mixed-Signal Circuitry
Product Category:
Waveform Generators
Plain-English Summary:
Circuits designed to generate triangular electrical waveforms with linear rising and falling edges.
Relation to Claims:
The patent's ramp controller outputs a ramp signal that starts, changes linearly based on a slope register, and stops, matching triangular or ramp waveform generation.
CPC H03K4/08
Confidence: High
Official Definition
Generating pulses having essentially a finite slope or stepped portions having triangular shape having sawtooth shape
ELECTRICITY > ELECTRONIC CIRCUITRY > PULSE TECHNIQUE
AI Technology & Product Mapping
