For example, in ultrasound applications, the DC offset from variable-gain amplifier (VGA) varies at different gains. Such a variable offset can introduce artifacts in ultrasound images especially in Doppler modes. Analog filter between ADC and VGA can be used with added noise and power. Digital filter achieves the same performance as analog filters and has more flexibility in fine tuning multiple characteristics. ADS5294 includes optional first-order digital high-pass (HP) IIR filter. Figure 46 shows the device block diagram and transfer function. (1) Figure 46. HP Filter Block Diagram Figure 47 shows the characteristics at k=2 to 10. Figure 47. HP Filter Amplitude Response at K = 2 to 10 |
