A typical input structure for an ADC with an input buffer is shown in Figure 3-31 for the AD9042 12-bit, 41 MSPS ADC. The effective input impedance is 250 Ω, and an external 61.9 Ω resistor in parallel with t
This transformer has a lower nominal step up ratio of about 2/1, and is optimized for use with lower noise resistance amplifiers such as the AD797. As can be noted from the figure, the general topology is similar to the previous transformer coupled preamp, but some details allow premium ...
High speed on-chip reference buffer with replica source follower is also included for linearity performance. The ADC was fabricated in a standard 130-nm CMOS process and an occupied silicon area of 0.95 mm u00d7 1.15 mm. Performance of 73 dB spurious-free-dynamic-range is measured at 160 ...
10 MSPS PulSAR® ADC. The circuit maximizes the AD7626 performance for high frequency input tones using theADA4932-1low power differential amplifier to drive the ADC. The true benefit of this combination of devices
Harmonic performance of these generators is typically not as good as the intrinsic linearity of a given ADC, mandating the need for additional filtering between the signal generator and the analog input to the ADC. Analog Signal Filter Both fixed frequency and tunable frequency band-pass filters ...
AN0021: Analog to Digital Converter (ADC) This application note describes how to use the Analog to Digital Converter (ADC) of EFM32 Gecko Series 0 and 1 devices to con- vert an analog input voltage to a digital value. Many aspects of the ADC, including inputs, references, and the ...
