6 FAQs about [Capacitors are standard equipment for Element Sar]

What is a small unit capacitor value for a SAR ADC?

Previously, a rather large unit capacitor value of 657 fF has been calculated for a 12-bit SAR ADC based on the thermal noise restriction and the fabrication error in the 0.35 μm CMOS process , and recently, a small unit capacitor value of 13.5 fF has been adopted for a 10-bit SAR ADC .

Are binary-weighted capacitors suitable for custom advanced node planar SAR ADC?

This work presents a framework to synthesize good-quality binary-weighted capacitors for custom advanced node planar SAR ADC. Also, this work proposed a parasitic-aware ILP-based routing algorithm, which can generate an optimized layout considering parasitic capacitance and capacitance ratio mismatch simultaneously.

How many LSB capacitors are needed for an n-bit SAR ADC?

For an N-bit SAR ADC, the conventional binary-weighted DAC array requires 2 N unit capacitors. The number of unit capacitors increases exponentially with N and they occupy a large area, causing large interconnection parasitism. In addition, the mismatch between the LSB capacitor and MSB capacitor also becomes larger.

Which capacitive DAC architecture is best for 10-bit SAR ADCs?

Abstract: This paper presents a detailed comparison between the two commonly used capacitive DAC architectures for 10-bit SAR ADCs: binary-weighted and split-capacitor DACs. These DAC architectures are compared based on the impact of unit-capacitor mismatch and parasitic capacitance on their linearity, area and power consumption.

What is a reliable minimum unit capacitor for a 10-bit SAR ADC?

The reliable minimum unit capacitor calculated for a 10-bit SAR ADC using 0.35 um process is about 90 fF in theory. Test results confirm the yield but DNL results are slightly bigger than the expected value of ½ LSB.

How many analog circuits are in a SAR ADC?

However, there are very few analog circuits in a SAR ADC. The SAR ADC is mainly composed of the dynamic comparator, the DAC capacitor array and the digital control logic, which is compatible with advanced CMOS processes. For an N-bit SAR ADC, the conventional binary-weighted DAC array requires 2 N unit capacitors.
