clamper circuit

i need DC level shifter thats clamper cicuit
in that i will give +2V to -2V as input and i have to get 0V to +4V
some of my friends r telling that dont use capacitor in ur design it will create more problem
please help me

dc level shifter circuit

Since the applicatgion is limited to 0 to 4 volt o/p and 2 to -2 volt input an OPAMP can conveniently be used. Put a +2 volt supply to the non-inverting amplifier and the input to the inverting amplifier through a 1k resistor. In the feedbac path use a same 1k resistor.

Depending on your curent requirement and load pecification you may need a buffer at the output of the circuit.
