The value of the input capacitor is important to consider as it directly affects the bass (low frequency)

performance of the circuit. Speakers in wireless phones cannot usually respond well to low frequencies, so the

corner frequency can be set to block low frequencies in this application. Not using input capacitors can increase

output offset. Equation 6 is used to solve for the input coupling capacitance. If the corner frequency is within the

audio band, the capacitors must have a tolerance of ±10% or better, because any mismatch in capacitance

causes an impedance mismatch at the corner frequency and below.
