Hi Andrew, I am using version 1.5: SCCS Info: @(#) abMovingAvg.il 07/17/16.15:14:54 1.5 I am using the moving average filter to removed the excessive spikes (glitches) in the waveform but its adding a dc offset to the steady state value when the signal is flat. for above plot, time window = 40ps gain = 1. To debug I tried it on a flat power supply voltage also, Vavcc = 0.88. With time window: 100ns -> MA voltage = 4uV error With time window: 1ns -> MA voltage = 440uV error With time window: 40ps -> MA voltage = 11mV error Regards Ben
