Using Equation 5, designers can precisely estimate the impact of phase noise on the ADC’s performance, taking into account the signal’s spectrum distribution.

You calculate the real SNR of an ADC using the fundamental input signal and the FFT bins that contain noise. Figure 1 shows the FFT plot of a 12-bit ADC with an input signal of 9.9 kHz. With the ...

Ideally, each code width (LSB) on an ADC's transfer function should be uniform in size. For example, all codes in Figure 2 should represent exactly 1/8th of the ADC's full-scale voltage reference. The ...

Low Power, Fully Differential 18-Bit ADC Driver. A low power, low noise, fully differential amplifier, ADA4940-1, is manufactured using SiGe complementary bipolar process, which is optimum for driving ...

Equation 3 provides the NF1 for a simple, non-inverting design with a resistor to ground as in Figure 1 (matched in these examples to a 50-Ω source): The “2” arises from achieving the match ...

[Simon Monk] got frustrated with bad ADC performance when tinkering with an ESP32 board, and decided to put three of the nowadays-iconic boards to the test – a classic ESP32 devboard, a Pi Pi… ...
