ABSTRACT:
An apparatus is provided which is responsive to a multiple bit sample of digital information for producing a pulse width modulated signal, the apparatus comprising: a first signal match detector, responsive to a first subset of the multiple bit sample, for producing a first signal that can transition between first and second logical states; a second signal match detector, responsive to a second subset of the multiple bit sample, for producing a second signal that can transition between the first and second logical states; and a voltage summing circuit for producing a first voltage that is substantially proportional to a magnitude of the first signal in one of the first logical state and the second logical state and for producing a second voltage that is substantially proportional to a magnitude of the second signal in one of the first logical state and the second logical state and for producing an output voltage that is substantially proportional to a sum of the first voltage and the second voltage.
