چکیده
4-bit high speed R-2R Ladder Digital to Analog Converter (DAC) design is presented in this paper. The high speed DAC design uses a high speed InGaAs/GaAs HEMT device in its summer block. This paper justifies the use of HEMT devices for high speed converter applications. A detailed analysis of the DAC parameters and errors is presented. DAC performance up to 20GHz is presented and it shows very good DNL and INL performance, and stable offset and resolution over the frequency range up to 20 GHz. Index terms DAC, DNL HEMT, INL, Linearity, Resolution, R-2R ladder, VLSB.

متن کاملDesign and Analysis of High Speed Capacitive Pipeline DACs
Design of a high speed capacitive digital-to-analog converter (SC DAC) is presented for 65 nm CMOS technology. SC pipeline architecture is used followed by an output driver. For GHz frequency operation with output voltage swing suitable for wireless applications (300 mVpp) the DAC performance is shown to be limited by the clock feed-through and settling effects in the SC array rather than by th...
متن کاملAn 11 GS/s 1.1 GHz Bandwidth Interleaved ΔΣ DAC for 60 GHz Radio in 65 nm CMOS
This work presents an 11 GS/s 1.1 GHz bandwidth interleaved ∆Σ DAC in 65 nm CMOS for the 60-GHz radio baseband. The high sample rate is achieved by using a two-channel interleaved MASH 1-1 architecture with a 4-bit output resulting in a predominantly digital DAC with only fifteen analog current cells. Two-channel interleaving allows the use of a single clock for the logic and the multiplexing w...
متن کاملA resistance matching based self-testable current-mode R-2R digital-to-analog converter
This paper presents a resistance matching based selftestable current-mode R-2R Digital-to-Analog Converter (DAC). The Built-In Self-Test (BIST) circuits are employed to observe the current redistributions in the resistance matching branches converted from the R-2R network in the DAC, and then the redistributed currents are transformed to voltages to detect the R-2R network with extra Design For...
متن کاملAn Area- and Power-Efficient Iref Compensation Technique for Voltage-Mode R-2R DACs
Although segmented voltage-mode R-2R DACs have been widely used for high-precision DACs in static applications, its code-dependent reference current induces a code-dependent IR drop through the reference and ground wires, imposing a limitation on the linearity performance. To alleviate this problem, this paper proposes a simple way to compute the reference current and compensate it via a low-re...
