Wireless Transceiver Chip Pin Count Reduction via Internal Switch Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high pin count of wireless transceiver chips hinders their miniaturization and complicates circuit layout, making it difficult to reduce chip size and facilitate communication with baseband chips.
Innovation Solution
Integrating a switch within the wireless transceiver chip to reduce pin count, allowing direct control for data transmission between the chip and the baseband chip, and enabling a calibration method using pattern signals to connect transmitters and receivers through different switches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the switch is provided externally to the wireless transceiver chip, then the switching function between transmitter and receiver is achieved, but the pin count of the chip becomes too large
Solution Approach 1:
The patent merges the externally provided switch into the wireless transceiver chip itself, integrating the switching function directly within the chip. This consolidation eliminates the need for separate external switch components and their associated pins, thereby reducing the overall pin count while maintaining the transmitter-receiver switching capability.
2Adaptability or versatility
If the pin count of the wireless transceiver chip is large, then the switching function is achieved, but the chip size cannot be reduced and circuit layout becomes more difficult
Solution Approach 1:
By integrating the switch within the wireless transceiver chip, the patent reduces the number of external connections and pins required. This integration simplifies the overall circuit layout by eliminating the need for complex external switching circuitry and reduces the chip size by consolidating functions into a single integrated component.
