1. Draw a circuit that can scale the voltage from the range of 0~200 mV to the range of 0 ~ 10V.
2. Draw a circuit that can scale the voltage from the range of -200 mV ~0 V to the range of 0 ~ 10V .
3. Draw a circuit that can scale the voltage from the range of 0V~10V to the range of 0 ~ 5V.
4. Draw a circuit that can scale and shift the voltage from the range of -8 V ~0V to the range of 0 ~ 5V.
