Centralized Calibration Manager for Multi-Radio Transceivers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current calibration methods for communication devices are complex and inefficient, especially for multi-radio transceivers, as they require customized logic for different types of calibrations, which occupies valuable IC space and is difficult to reuse across designs.
Innovation Solution
A centralized calibration manager that receives information on component calibration needs, sets trigger conditions based on various factors like time, temperature, and system changes, and executes calibrations accordingly, using software to manage and schedule calibration routines across multiple radio protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If customized calibration logic is provided for each type of calibration, then calibration accuracy is improved, but IC space is consumed and device complexity increases
Solution Approach 1:
The patent implements a universal calibration manager that can handle multiple types of calibrations (frequency, gain, phase, offset) through a single integrated block. This calibration manager receives calibration requests for different radio protocols and performs the appropriate calibration using shared hardware resources, eliminating the need for separate customized logic for each calibration type while maintaining calibration accuracy.
2Measurement precision
If customized calibration logic is provided for each type of calibration, then calibration accuracy is improved, but device complexity increases
Solution Approach 1:
The calibration manager acts as an intermediary between the radio protocol layers and the calibration hardware. It receives calibration requests from different radio protocols, determines the appropriate calibration type, and executes the calibration using shared resources. This intermediary layer simplifies the overall system by providing a unified interface and centralized control, reducing the complexity that would otherwise arise from having multiple customized calibration logic blocks.
3Adaptability or versatility
If separate calibration logic is provided for each radio protocol, then calibration adaptability is improved, but ease of manufacture deteriorates
Solution Approach 1:
The calibration manager is designed as a universal block that can adapt to different radio protocols and calibration requirements through software configuration rather than hardware customization. The same calibration manager hardware can serve multiple radio protocols (GSM, WCDMA, LTE, etc.) by receiving protocol-specific calibration requests and executing the appropriate calibration routines, thereby improving both adaptability and ease of manufacture through design reusability.
