摘要:
采用累积误差实时数字补偿技术,当温度误差累积时间达到1个时钟周期时,在产生1 Hz频率方波的计数器上采取相应的操作,少加一次或者多加一次来补偿之前的频率总误差,使实时时钟在-40~85℃动态温度范围内的精度达到5.0×10-7.仿真结果表明,1 a的时间时钟最大误差不到1 min,累积误差实时补偿的方法达到期望的补偿精度.
Abstract:
Adopting accumulative error timely digital compensate technical,the counter which to produce 1 Hz square wave compensate the previous total error by corresponding operation that counting a more time or less time when the accumulative error up to 1 clock cycle.It can guarantee the precision of 5.0×10-7 in the temp range of-40~85 centigrade.The simulation results suggest that the maximum error of the clock is less than 1minute during 1 year,and the accumulative error timely accumulate method attains the anticipate precision.
