R4396.01, EAO: kaf, LONG TIME CONSTANT INTEGRATING CIRCUIT ABSTRACT, A method and apparatus for performing integration using a circuit capable of integrating an input signal over a wide linear dynamic range. The circuit modulates the input signal with a biphase signal having positive and negative phases. The modulated signal is then provided to an integrator. The integrator operates continuously within its linear range without needing charge dumping because the amplitude of the modulated signal is less than the amplitude required to saturate the integrator. Each interval of the integrated signal corresponding to positive and negative phases of the biphase signal is then partitioned into …

Why it's free to use
- Granted July 30, 1991. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended July 30, 2008.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
