There is an input signal Vi that varies in the range [-1,1]. The goal is to have the following output signal: Vo = 10UnitStep(Vi) Vi. Design a circuit that generates Vo(Vi) (if Vi ≥ 0, UnitStep(Vi) = 1; if Vi < 0, UnitStep(Vi) = 0).

I am using 2 op-amps. The first op-amp has V_i at the non-inverting terminal and inverting terminal is grounded. I am feeding the output into the non-inverting input of a non-inverting amplifier. Will this work for the requirements? Thanks for your help.

 

Would something like this work?

 

Thank you for your reply. I will definitely test it out. Thanks again!
