Final answer:
To calculate the worst-case output voltage, we need to calculate the minimum PSRR required for the ripple effects to be lower than 20μVpp. PSRR is the measure of how well an amplifier rejects changes in the power supply voltage. By calculating the PSRR value, we can determine whether the ripple effects will be lower than the specified threshold value.
Step-by-step explanation:
To calculate the worst-case output voltage for these conditions, we need to calculate the minimum Power Supply Rejection Ratio (PSRR) required for the ripple effects to be lower than 20μVpp. PSRR is the measure of how well an amplifier rejects changes in the power supply voltage.
To calculate PSRR, we need to know the ripple voltage of the power supply and the minimum acceptable ripple voltage at the output. In this case, the ripple voltage is given as 0.7 V and the minimum acceptable ripple voltage at the output is 20μVpp.
The PSRR can be expressed both in linear units or in dB units. In linear units, PSRR is calculated as the ratio of the change in output voltage to the change in input voltage. In dB units, PSRR is calculated as 20 log (change in output voltage/change in input voltage). By calculating the PSRR value, we can determine whether the ripple effects will be lower than the specified threshold value of 20μVpp.
