Hello all,
I am generating a ramp from 0 to 1V with 10mV steps using a differential switched cap integrator. But my requirement is to generate a ramp from -0.1V to 0.9V. How will I be able to provide this offset in the circuit?
 

The circuit element that provides now the zero volt initial condition should be modified. No detailed suggestion in lack of a schematic in your post.
 

The key is that your initial conditions or reference to be at -0.1 instead of 0 volts.
If you are -most likely- using an opamp, then its VEE connection will have to be supplied from a small negative voltage, usually -0.7 volt.

However, without a schematic, hard to provide additional suggestions.
 

How about using a buffered DAC to achieve this - faster and easier I would have thought ...?
