AN-1558 Clocking High-Speed A/D Converters (Rev. B)
Texas InstrumentsExtremely high-speed ADCs (>1 GSPS) demand a low-jitter sample clock in order to preserve signal-tonoiseratio (SNR). These 8- and 10-bit converters have best-case noise floors set by quantization noise.For an N-bit ADC sampling a full-scale sinusoid the well known expression for SNR (in dB) is: SNR =6.02N + 1.76. This sets the best case noise floor for an 8-bit ADC at −49.9 dBc. The noise f

Building a Simple SPICE Model for the THS3001
Texas InstrumentsThe application report Voltage Feedback Versus Current Feedback Op Amps SLVA051 outlines the basic operation of a current feedback operational amplifier (op amp) in relation to a voltage feedback op amp. One of the basic principles of a current feedback op amp is that its transfer function is a transimpedance equal to the output voltage divided by the current from the negative input terminal i.e.
Tuning VCP2 and TCP2 Bit Error Rate Performance
Texas InstrumentsIn most customer applications a high level of decoding bit error rate (BER) performance is required. Since Convolutional codes and Turbo codes are widely used in wireless communication systems TI DSPs integrate two high-performance embedded coprocessors (enhanced Viterbi decoder coprocessor and enhanced Turbo decoder coprocessor) that significantly speed up channel-decoding operations on-chip.
