This technique can maximize the SFDR
and reduce the size of the coefficients ROM.
However as the peak input signal swing for both the input signals is set to half of the full scale value the two tone SFDR
is 6 dB less than single tone SFDR
The SNDR and SFDR
of F&I ADC are greater than 37 dB up to 500 MHz at 1 GS/s, and the INL and the DNL are less than [+ or -]0,6 LSB and [+ or -]0,4 LSB, respectively.
The AD9648 is a low-power, high-speed, 14-bit dual A/D converter that consumes 102 mW/channel at 125 MSPS (mega samples per second) and features SFDR
(spurious-free dynamic range) performance of 91dBc at 70MHz.
Calculate the inter-stage RF power loss between two adjacent devices with mismatched impedance levels; voltage domain signal levels such as rms voltage, peak-to-peak voltage, and noise spectral density in nV/?Hz; and signal quality metrics such as SNR, SFDR
, IMD, and ACLR
To replicate real-world signal behavior, the series can generate signals up to 1 GHz of modulation bandwidth with 54 dBc, 2.5 GHz of modulation bandwidth with 46 dBc spurious free dynamic range (SFDR
At 70MHz and 80MSPS, it achieves an SNR (signal-to-noise ratio) of 73.7dBFS and an SFDR
(spurious-free dynamic range) of 92dBc.
-- A 1- to 6-dB programmable gain option gives customers flexibility to trade off between SNR and spurious free dynamic range (SFDR
) with lowered input voltage swing.
To this end, the static flexible deformable ring (SFDR
), PWDS, and DSM techniques are used in the industry.
Simulation results show that a spurious-free-dynamic range (SFDR
) of 94/78 dB can be achieved in WCDMA/WLAN mode.
This high dynamic range of the signal has huge impact on various performance metrics such as signal-to-noise ratio (SNR) and Spurious Free Dynamic Range (SFDR
Texas Instruments has announced a 13-bit, 210MSPS analog-to-digital converter (ADC) featuring 68dB signal-to-noise ratio (SNR) and 79dB spurious-free dynamic range (SFDR
), at the maximum sample rate of 210MSPS and an input frequency of 230MHz.
