  • Single shot sigma-delta analog to digital converter
    Patent number: 5189419
    Abstract: A sigma-delta analog to digital converter 1 is disclosed. The digital filter comprises digital integrators (8, 10) for reception of the negative feedback signal of the analog modulator. The digital integrators (8, 10) are connected to replicate processing of the feedback signal by the analog integrators (3, 5). Accordingly, the digital filter and the analog modulator may be reset simultaneously so that there is no time lag between conversion cycles. Thus, single shot operation is achieved.
