| Abstract: | A high-speed high-accuracy partially-cascaded A/D converter is developed, which is used with the telescope for observing the solar magnetic field. The major techniques employed for realizing high speed and high accuracy are discussed, and some related factors are also considered.For this converter, the word length is 12bit, the resolution power is 1 mV, the relative accuracy less than 0.025%, and the rate is 100,000 sec-1 when a sampling hold circuit is cascaded in front of it. |
