<p>The device has two silicon microphones (2, 3), and two impedance converters (4, 5) connected with one of the microphones, where the converters and the microphones are designed on a single chip (1). Power supply units of each converter are connected with a power supply terminal (V mic), and earth terminals of each converter are connected with a common earth terminal (GND) of the chip. The supply inputs and the earth terminals of the converters are connected with each other. Each of the converters has output terminals at a side of the chip.</p> |
