The Wheatstone Bridge-based Analog Adaptive Filter With Application In Echo Cancellation
Year
: 2009
Abstract: In this paper, a new analog adaptive filter is
introduced with application in adaptive echo cancellation
namely, the Wheatstone bridge-based analog adaptive filter
(WAAF). It is proved the WAAF is a variable weight
analog IIR filter. IIR filter weights vary with gate-source
voltage control of a MOSFET transistor in triode region.
The best balance point control of the WAAF is achieved
using least mean square (LMS) algorithm. It is proved that
analog LMS algorithm converges faster than digital LMS
adaptive filter. The superiority of the proposed WAAF is
observed in the designing process, computational cost,
convergence speed and real time operation. Also, experimental
results show ability of the proposed WAAF in the
hybrid circuit of the telephone echo cancellation.
