Abstract

Audio interfaces are among the most popular interfaces between man and machines. Such interfaces are based on microphones, whose efficiency expressed in terms of performance/power consumption is becoming one of the crucial parameters for the success on the market. In this chapter, the main specifications of typical microphone interfaces are illustrated to exhibit the advances in their development toward the maximization of their efficiency.

Fußnoten
1
To achieve 20 Hz cutoff frequency with a 10-kΩ input resistance, the AC-coupling caps must be of the order of 1 μF. While 1-μF ceramic capacitors are widely available even in very small form factor, their large voltage coefficient can create a significant nonlinearity at low frequencies. For this reason, it is strongly preferable to utilize capacitors in the order of 10 nF, which requires a preamplifier input impedance in the order of 1 MΩ.
