the system (unless this capacitance can be
measured and taken into account). R must be much
larger than the COS/MOS ”ON” resistance in series
with it, which typically is hundreds of ohms. In addi-
tion, with very large values of R, some short-term in-
stability with respect to time may be noted.
The recommended values for these components to
maintain agreement with previously calculated for-
mulas without trimming should be :
