“…It is a useful parameter for assessing the performance of ADCs and DACs for communications systems. The theory is described in [5] For an ADC, the measurement uses a Gaussian noise source and a notch filter to remove the noise signal in the band of interest. A DAC test system will generate the test pattern in the digital domain.…”

The ability of the new generation of Digital to Analog Converter (DAC)s to convert from a digital signal directly into high frequency bands can be seen as a large leap in capability allowing greater system flexibility, reduction in component footprint and power consumption. This paper presents a new high speed, high bandwidth Digital to Analog Converter with high sample rate and high output bandwidth which enables the direct conversion of signals to frequencies up to band X. The component features a number of innovative design features which enable the optimization of performance in the different Nyquist zones. These include various output shaping schemes and interface methods. Results will be presented which show the performance of the circuit at output frequencies greater than 8GHz. The component's performance can result in highly flexible and waveform agile Radar signal generation systems.

This paper presents the new Passive Radar and Signal Intelligence signal chain possibilities that are created by the latest 12-bit 4.5GSPS ADC development. It focuses on a new high speed, high resolution Analog to Digital Converter (ADC) with high input bandwidth which enables the direct RF down conversion up to S-band. It allows new perspectives for application such as Passive Radar and Signals Intelligence.

“…2) 12 Bit 3GS/s DAC NPR@3GS/s with 900MHz wide pattern Noise Power Ratio (NPR) is probably the most relevant figure to reflect the usability of a device in real condition of operation (digitizing or synthesizing of broadband signals), theory is clearly explained by Walt Kester [11], and [10], [12]. By duality NPR is also applicable either to ADC or DAC.…”

“…See References [10], [11], [12]. For an ideal ADC, only the quantification noise is taken into account to compute the NPR: the relationship between broadband NPR and single tone SNR is given by:   Therefore it is shown that there is a strong correlation between small signal single tone ENOB (SINAD) and NPR.…”

This paper describes design techniques for Bipolar and BiCMOS analog circuits. Comparison on such performances as transconductance, speed, matching, noise of bipolar and CMOS transistors are reviewed and compared. Design achievements such as a single core 12 Bit 1.5GS/s Analog to Digital Converter (ADC) [1] and a single core 12 Bit 3GS/s Digital to Analog Converters (DAC) [2] based on a fully bipolar 200GHz SiGeC technology are introduced to illustrate the advantages and drawbacks of a fully bipolar technology for high speed data converters. A Quad 10 Bit 5GS/s ADC based on 4 interleaved ADC Core designed with a 120 GHz 0.18um BiCMOS technology is also presented, to illustrate the advantages brought by the combination of Bipolar and CMOS technologies.
