The Simple Sigma-Delta Analog-to-Digital Converter Reference Design targets the implementation of an analog-to-digital converter in a Lattice CPLD or FPGA. This reference design supports the use of an external analog comparator device, or optionally an on-chip LVDS buffer in devices with differenti...
The paper presents the design of a single-ended amplifier in 1.8 V, 180 nm CMOS process for buffering the reference voltage in a 10-bit 1-MS/s successive-approximation register (SAR) ADC. The design addresses the comprehensive requirements on the buffer such as settling time, PSRR, noise, ...
This reference buffer design requires three devices, and a large number of external components. This solution still consumes close to 2 mA of quiescent current. 5-V Power Supply Temp VIN VOUT REF5045 Temp GND Trim 1 µF 1 NŸ 200 PŸ 10 µF 1 µF VDD + OPA333 1 µF 1 ...
The reference voltage source design must provide a low output impedance (static and dynamic). The parasitic serial resistance and inductance must be minimized. Correct decoupling capacitors on the reference voltage located very close to pins provide a low reference voltage source impedance. Anal...
And similar to input, some of the new age SAR and DTSD ADCs also have the option of an integrated reference buffer, but they come with performance and bandwidth limitations. MCLK The CTSD ADC advantage: This design step can be completely skipped by using a CTSD ADC as it provides a new,...

V/I converter)。一般流水线ADC需要正负两个参考电平，因此需要电平移位电路(Voltage shifter)产生所需的电压。为了保证高速高精度的对电容的冲放电，参考电压必须要采用缓冲器来(Reference buffer)得到必需的精度和建立时间。最后还需要低通滤波器(LPF)来达到系统输出的低噪声。整个系统架构如图1所示。
