Abstract :
A distortionless syllabic companding filter can be obtained theoretically by updating the state variables of the filter as a function of the compression signal. In translinear filters, this is accomplished by adding a compensation current to all the capacitors in the filter. This current can be generated using only one capacitor and one transistor. Simulation results of a translinear syllabic companding differential filter are presented
