Continuing from the episode 14, introducing details of sampling operation of SAR type and ZDS ADC. #15 Basic Knowledge of ADC This is a story that young A, who works in a fictional motor company deepens the knowledge of ADCs with a senior colleague K, and his boss, M, manager.

The 10-bit 10-MS/s single-ended asynchronous SAR ADC using the proposed CDAC is implemented by using a 180-nm CMOS process with a supply voltage of 1.8V. Its active area and power consumption are 0.207mm2 and 2.29mW, respectively. The measured DNL and INL are +0.93/−0.51 SAR ADC Considerations contd. •Comparator offset V os introduces an input-referred offset ~ (1+C P /ΣC j)*V os •C P in general has little effect on the conversion (V X→0 at the end of the search) •however, V X is always attenuated due to charge sharing of C P •Binary search is sensitive to intermediate errors made during search – A 90GS/s 8b low-power ADC is presented achieving 33.0-36.0dB SNDR and a FoM of 203fJ/conversion-step.

SAR ADC 5/21/2018 Yuan Mei Figure 2. SAR operation (4-bit ADC example) Notice that four comparison periods are required for a 4-bit ADC. Generally speaking, an N-bit SAR ADC will require N comparison periods and will not be ready for the next conversion until the current one is complete.

ADC operation except for repeating the least significant bit (LSB) comparisons. A useful property of an SAR ADC is that the comparator input voltage is the

II. DUAL CHANNEL SAR ADC Hello and welcome to the TI Precision Lab covering SAR ADC drive amplifier considerations when using operational amplifiers. Overall, this video will cover how to design the op amp drive circuit for linear operation. Specifically, we will learn how op amp common-mode range and output-swing limitations can impact SAR ADC performance. OGAWA et al.: SAR ADC ALGORITHM WITH REDUNDANCY AND DIGITAL ERROR CORRECTION 417 Fig.4 Redundant search algorithm of a 5-bit 6-step SAR ADC (case 2).

SAR ADC • DAC Controller stores estimates of input in Successive Approximation Register (SAR) • At end of successive approximation process, ADC output is in SAR • Eliminates the power-consuming amplifiers of the pipelined ADC • Much slower than pipelined ADC • S/H at the input is essential • Can have excellent power performance A successive approximation ADC works by using a digital to analog converter (DAC) and a comparator to perform a binary search to ﬁnd the input voltage. A sample and hold circuit (S&H) is used to sample the analog input voltage and hold (i.e. keep a non-changing SAR ADC Considerations contd. •Comparator offset V os introduces an input-referred offset ~ (1+C P /ΣC j)*V os •C P in general has little effect on the conversion (V X→0 at the end of the search) •however, V X is always attenuated due to charge sharing of C P •Binary search is sensitive to intermediate errors made during search – The SAR ADC is the commonly used architecture for data acquisition systems that are widely employed in medical imaging, industrial process control, and optical communication systems. In these applications, we usually need to digitize the data generated by a large number of sensors.
