Description: Easy-to-Use, Ultra-Tiny, Differential, 16-Bit Delta Sigma ADC With I2C Interface
The LTC2453 is an ultra-tiny, fully differential, 16-bit, analog-to-digital converter. The LTC2453 uses a single 2.7V to 5.5V supply and communicates through an I2C interface. The ADC is available in an 8-pin, 3mm x 2mm DFN package. It includes an integrated oscillator that does not require any external components. It uses a delta-sigma modulator as a converter core and has no latency for multiplexed applications. The LTC2453 includes a proprietary input sampling scheme that reduces the average input sampling current several orders of magnitude lower than conventional delta-sigma converters. Additionally, due to its architecture, there is negligible current leakage between the input pins.

A PLD Based Delta-Sigma DAC
Delta-Sigma modulation is the simple, yet powerful,
technique responsible for the extraordinary
performance and low cost of today s audio CD
players. The simplest Delta-Sigma DAC consists of a
Delta-Sigma modulator and a one bit DAC. Since,
both of these components can be realized using
digital circuits, it is possible to implement a low
precision Delta-Sigma DAC using a PLD.-Using FPGA to achieve the DA converter, has descriptions and source code, VDHL document.

Description: Compute the output of a general delta-sigma modulator with input u,
a structure described by ABCD, an initial state x0 (default zero) and
a quantizer with a number of levels specified by nlev.
Multiple quantizers are implied by making nlev an array,
and multiple inputs are implied by the number of rows in u.
Alternatively, the modulator may be described by an NTF.
The NTF is zpk object. (The STF is assumed to be 1.)

Description: Determine the SNR for a quadrature delta-sigma modulator using simulations.
The modulator is described by a noise transfer function (ntf)
and the number of quantizer levels (nlev).
The ntf/stf may be given in ABCD form.
The band of interest is defined by the oversampling ratio (R)
and the center frequency (f0).
