Main Inventor

Christer Jansson

Brief explanation

The abstract describes a method for stabilizing the bias voltage in a pipelined Successive Approximation Register Analog to Digital Converter (SAR ADC) by tracking Process, Temperature, and Voltage (PVT) variations. The method involves generating a PVT-dependent bias voltage that is used to bias the inputs of comparators in the SAR ADC. This ensures a stable operating point for the comparators and input stages, regardless of PVT variations. 

• The method generates a PVT-dependent bias voltage to stabilize the biasing of comparators in a SAR ADC.
• The PVT-dependent bias voltage tracks PVT variations to counteract variations in MOS threshold voltage and drain-source voltage.
• A threshold common mode voltage is generated from the PVT-dependent voltage to control the amplification duration of the residual amplifier (RA).
• The threshold is set to account for logic delays in terminating the amplification, ensuring the desired common mode amplifier output.
• The dependency of the threshold on PVT cancels out temperature variation from a differential stage transconductance of the RA.
• Temperature stabilization is further achieved by boosting the charge output by the RA to a capacitive load during part of the amplification.

Potential Applications

• Analog to digital converters (ADCs)
• Integrated circuits requiring stable biasing and operating points

Problems Solved

• Instability of bias voltage in SAR ADCs due to PVT variations
• Variations in MOS threshold voltage and drain-source voltage affecting the operating point of comparators and input stages
• Temperature variation affecting the differential stage transconductance of the residual amplifier

Benefits

• Stable biasing and operating point of comparators and input stages in SAR ADCs
• Compensation for PVT variations to counteract MOS threshold voltage and drain-source voltage variations
• Temperature stabilization of the differential stage transconductance in the residual amplifier
• Improved accuracy and reliability of analog to digital conversion.

Abstract

In a pipelined Successive Approximation Register Analog to Digital Converter, SAR ADC, a Process, Temperature, and Voltage (PVT)-dependent bias voltage is generated and used to bias the inputs of comparators in at least the first SAR stage and residual amplifier (RA). This achieves a stable biasing and an operating point of the comparators and RA input stages that is independent of PVT variations, by tracking PVT variations in such a way that variations in MOS threshold voltage and drain-source voltage are counteracted. Additionally, a threshold common mode voltage is generated from the PVT-dependent voltage, which controls the amplification duration of the RAs such that the final RA output common mode voltage is substantially equal to the PVT-dependent voltage, which is used to bias the inputs of successive SAR stages. The threshold is set to account for logic delays in terminating the amplification based on the threshold comparison, to achieve the desired common mode amplifier output. The dependency on PVT of the threshold additionally cancels temperature variation from a differential stage transconductance of the RA. Further temperature stabilization is achieved by boosting the charge output by the RA to a capacitive load during part of the amplification.
