Given that the precison temperature sensor produces an output voltage (VS: sensor Output Voltage) according to the equation Vs = (12mV) T°C + 1.8V This equation can be expressed in terms of temperature (T) versus sensor Voltage (Vs).ie T=(Vs - 1.8) / (0.012) You are to design the amplifier circuit for this sensor using any combination of inverting amplifiers, non-inverting amplifiers, summing amplifiers (No need to use all types of amplifier ) together with a 1V Reference voltage source. The sensor voltage (Vs) and a 1V reference voltage (Vref) are the two input signal of your circuit. Your designed circuit should produce an output voltage (Vo) to indicate the temperature accordingly to the equation Vo = T/10. (°C/10) ie. When T=0 °C, Vo= 0V and T=100 °C, Vo = 10V I need to design a circuit using Op-amp.

so i need to offset the voltage of -1.8v. a summing amplifier is used and also put an inverting stage before the summer.. to change the polarity..
