GENERATION OF A TIME PERIOD |
摘要 |
The invention generates a time period (Td) with a high accuracy and a high resolution. At a starting instant (ti) of the time period (Td), an analog integration operation (3) is started to generate an integration value (ios). At a certain instant (t1), the analog inegration operation (3) is interrupted to start counting (2) clock pulses (C1k). A selected number (N;N2) of clock pulses (Clk) is counted to obtain a sub-period (T2). The analog integration operation (3) is resumed at the end of the sub-period (T2) at the integration value (ios) reached at the start of the sub-period (T2). The analog integration operation (3) finishes at an end instant (td) of the time period (Td) at which the integration value (ios) crosses a reference value (Ref).
