Solution Overview
Problem
RF transceivers often require specific components that may not be necessary for optimal performance in all instances, leading to inefficiencies in power consumption and system performance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high-performance components (e.g., LC VCO) are used in the receiver and transmitter, then system performance is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic component selection where the receiver and transmitter can switch between different oscillator types (LC VCO, ring VCO, low power oscillator) based on current operating conditions. The DSP monitors system performance and selectively activates components, allowing the system to adapt its power consumption and performance characteristics in real-time rather than being fixed at design time.
Solution Approach 2:
The system changes operational parameters by selecting different component configurations based on monitoring information. The DSP adjusts which components are active (e.g., switching between high-performance LC VCO and low-power ring VCO) depending on performance requirements, effectively changing the system's power-performance parameter profile dynamically.
2Reliability
If multiple components are always activated to ensure optimal performance, then system reliability is improved, but power consumption and device complexity increase
Solution Approach 1:
The system performs self-configuration through the DSP which monitors operating parameters and automatically selects appropriate component settings. The transceiver self-adjusts its component activation based on real-time performance monitoring, eliminating the need for manual configuration and reducing the effective complexity of managing multiple components.
Solution Approach 2:
The DSP serves multiple functions: it processes signals, monitors system performance, determines optimal component configurations, and controls component activation. This multi-functionality consolidates control logic into a single intelligent unit, reducing overall system complexity despite the presence of multiple configurable components.
3Reliability
If high-performance components are designed into the system, then maximum performance is achieved, but power consumption increases and components may not be necessary for all operating conditions
Solution Approach 1:
The system applies partial action by activating only the necessary high-performance components when needed rather than continuously. The DSP determines the minimum required performance level and activates components accordingly (e.g., using low-power oscillators for normal operation, switching to high-performance LC VCO only when performance thresholds require it).

AI summary
A configurable transceiver may include a configurable receiver, a configurable transmitter, and a digital signal processor (DSP). One or more components of the configurable receiver and/or the configurable transmitter may be a block that includes an array of components, such as an array of amplifiers, an array of filters, etc. The DSP may determine a configuration of the configurable receiver that satisfies a bit error rate threshold and minimizes power consumption. The DSP may configure the blocks of the configurable receiver in accordance with the determined configuration of the configurable receiver. The DSP may receive an indication of a modulation scheme being used for transmitted data and may determine a configuration of the configurable transmitter for the modulation scheme that satisfies an error vector magnitude threshold and minimizes power consumption. The DSP may configure the blocks of the configurable transmitter in accordance with the determined configuration of the configurable transmitter.
