摘要： Complete testing of an analog-to-digital converter (ADC) can be carried out using digital signals and at high speeds. Circuit elements are added to an ADC so that a first phase of testing may be carried out using a limited number of analog test voltages. The ADC may then be reconfigured using added circuit elements to disable conventional analog-to-digital conversion. A digital signal may then be applied to the ADC to rapidly test all switching elements used in analog-to-digital conversion. According to some implementations, testing times for ADCs may be reduced from hours to milliseconds.

摘要： A circuit is adapted to activate a writer head of a data storage media drive during both the boost periods as well as the steady state periods. The current supplied to the writer head during the boost periods exceeds the steady state current and flows between positive and negative voltage supplies so as to provide the required magnetic flux change in the inductor disposed in the write head. During the steady state periods, a switch circuit is turned on to provide a second current path across the writer head. During the steady state periods, the current flows between the positive voltage supply and the ground to reduce power consumption. The switch circuit is turned off during the boost periods.
