Abstract
The voiceband downlink described in this paper is a part of a wireless CODEC. It relies on a Sigma-Delta modulator followed by a 1 Bit current mode DAC including an FIR filter. This new architecture results in very low power consumption. The design of the CODEC and actual test results are given.
