A lOBIT 40MHz ADC USING 0.8~ BI-CMOS TECHNOLOGY

A lObit ADC has been developed using 0.8um Bi-CMOS technology. In order to reduce power dissipation and chip size, two-step parallel type conversion scheme is adopted. lObit resolution has been realized at the maximum conversion rate of 4OMHz, power dissipation of 7OOmW and chip size of 4.1~4. 8mm2.
