A highly-digital technique is proposed for excess loop delay (ELD)
compensation in multi-bit continuous-time ΔΣ modulators. A digitally
controlled reference switching matrix is used to replace the power-hungry
signal adder and extra DAC driving the quantizer, which are
commonly used in ELD compensation. With the proposed technique,
the feedback DAC...

Extended-counting A/D converters are proposed which achieve a high
accuracy by performing the conversion in several cycles. During the
first cycle, the circuit performs as an incremental ADC, while during the
remaining ones it acts as a multi-slope counting converter. With only
one opamp and a single-slope ADC, the accuracy...
A new incremental ADC is proposed which extends the order of a
conventional incremental ADC from N to (2N-1) by way of a two-step
operation. For a given conversion time, the duration of each step can be
optimized. For an Nth-order IADC, the performance is equivalent to that
of a...
In this letter, a simple and highly efficient successive-approximation
Registers (SAR) ADC realization is proposed. It requires an op-amp,
a comparator and only three equal-valued capacitors. The proposed
scheme is insensitive to the capacitor parasitics, and has a small
capacitance spread. With an oversampled scheme, it also allows
noise-shaping the...
With the expansion of transport, increasing car ownership, rapid increase in outbound travel and new interests in nature based eco-tourism, and the adoption of 5 work days, marine eco-tourism is expected to have a very promising future and need more detailed preparation and planning. While marine eco-tourism occupies 30% of...
