This technology is an electronic circuit that uses dynamic biasing for reducing power consumption while enhancing signal extraction from a high-noise environment.
To conserve energy in electronic circuits, it is preferable to use bias currents that are no larger than necessary. Amplitude-dependent bias currents are often desirable as the minimum required bias current typically depends on signal amplitude, and amplitude-dependent biasing produces the least amount of noise when the bias current is only as large as needed. However, the bias can undesirably interact with the signal. Thus, to gain the benefits of reduced power consumption and minimal noise, there is a need for circuits in which the bias control and the signal properties do not interact with each other.
This technology uses dynamic biasing in circuits to improve signal conditioning and processing while reducing power consumption. This circuit can accommodate a range of signal amplitudes while maintaining high energy efficiency, high signal-to-noise ratio, and preventing interaction between the signal and bias control. Bias currents are adjusted in accordance with signals that are received or generated by the circuit. This approach can be implemented in various configurations to meet application-specific requirements without adding complexity to the circuit design.
This technology has been validated through extensive simulations and measurements.
