“…1, the output current delivered to the load can be expressed as I out = I ref0 2 10 w 0 + I ref1 2 10 w 1 + I ref2 2 10 w 2 + I ref3 2 10 w 3 (12) Since the reference amplifier has a wide linearity range in which the reference currents generated are proportional to their input signals, I ref0 = k · x n , I ref1 = k · x n−1 , I ref2 = k · x n−2 and I ref3 = k · x n−3 . The output current can be rewritten as…”

“…In reference [12], minimum differential voltage is used for complete steering of the reference current by making the differential voltage proportional to absolute temperature (PTAT). Reference [11] develops some techniques to isolate each current source using low-pass filter networks and multiple buffers to supply the gate bias voltage.…”

“…However, segmented DACs take large chip area and require complex decoding logic. Therefore, most high speed, high resolution DACs use a combination of segmentation and binary weighting [10][11][12]. Over the years, different design techniques have been developed to deal with different glitch sources.…”

This paper proposes a fast settling reference amplifier for use with a current-steering Digital-to-Analog Converter (DAC). The reference amplifier utilizes an open loop architecture, resulting in a bandwidth of 2.5 GHz, small chip area and low power. The wide bandwidth of the reference amplifier is shown to be important for fast settling of DAC current output. The reference amplifier is also able to generate a reference current that tracks fast changes of reference voltage, thus is useful in applications such as multiplying DACs and transversal filters. The proposed design was fabricated using a 1 µm GaAs HBT process. The prototype reference amplifier achieves a temperature coefficient of 92 ppm/ • C over a temperature range of 0-100 • C and the reference current changes only ±2.14% when the power supply varies ±0.2 V.

“…Further, a frequency response with a large Spurious Free Dynamic Range (SFDR) is required to satisfy the condition of highquality video communication systems [5,6]. In order to implement this requirement, intrinsic accuracy techniques [7,12], low deglitching circuits [8,11,14,15], a self-trimming technique [13], matrix cell relocation technique [9,10], and so many papers have been published.…”

“…However, the most widely used design technique is a current steering type [3][4][5][6][7][8][9][10][11][12][13][14][15], because it has the capability of driving resistive loads without any special buffers like operational amplifiers and suitability of simple CMOS implementation. Further, it is possible to implement with a high-speed operation and it consumes low power in comparison with other types.…”

A fully integrated current-steering 10-b CMOS Digital-to-Analog Converter with internal termination resistors is presented. In order to improve the device-mismatching problem of internal termination resistors, a selfcalibrated current bias circuit is designed. With the self-calibrated current bias circuit, the gain error of the output voltage swing is reduced within 0.5%. For the purpose of reducing glitch noises, further, a novel current switch based on a deglitching circuit is proposed. The prototype circuit has been fabricated with a 3 V 0.35 µm 2-poly 3-metal CMOS technology, and it occupies 1350 × 750 µm silicon area with 45 mW power consumption. The measured INL and DNL are within 0.5 LSB, respectively. The measured SFDR is about 65 dB, when an input signal is about 8 MHz at 100 MHz clock frequency.
