High-speed communication systems and technologies are an inseparable part of modern life, where they enable**a range of applications from self-driving cars to high-speed home networks for Internet and video services.**These service providers are always in need for new technologies to boost the bandwidth and increase the**number of channels and data without paying a prohibitive penalty in size and power dissipation. High-speed**communication technologies require fast circuit components for their realization, regular operation, and**payload testing. Among a variety of electronic components, analog to digital converters (ADCs) play a critical**role that is essential for modern high-speed communication systems. ADCs enable digital signal processors**(DSPs) to eliminate electronic noise and distortion and retrieve high quality signals by converting analog**signals to digital form. Recently, complementary metal oxide semiconductor (CMOS) technology has offered**transistors with shrinking channel sizes down to 22nm that allow for ultra high speed switching and digital**processing performance. However, in the analog domain, their performance can be limited due to lower gain**and output impedance compared to other alternatives. In this proposal, we will design, simulate, fabricate, and**test a high-speed, high resolution ADC for high data rate communication purposes (ie. 1-5 Gsps). The**following challenges will be studied in the course of this proposal and potential solutions will be investigate: a)**Fabrication technology, system structure and processing units versus performance; b) Compatibility of the**newly designed ADC with MaxLinears current signal chain. The design and implementation of an ADC with**the mentioned aspects enabling the Canadian division of Maxlinear to bring further development and**opportunities to Canadian Society.

高速通信系统和技术是现代生活不可分割的一部分，它们可以实现从自动驾驶汽车到用于互联网和视频服务的高速家庭网络的一系列应用。这些服务提供商总是需要新技术来提高带宽，增加通道和数据的数量，而不会在尺寸和功耗方面付出高昂的代价。高速 ** 通信技术需要快速的电路元件来实现、正常运行和有效载荷测试。在各种电子元件中，模数转换器（ADC）扮演着现代高速通信系统必不可少的关键角色。ADC使数字信号处理器 **（DSP）能够消除电子噪声和失真，并通过将模拟 ** 信号转换为数字形式来检索高质量信号。最近，互补金属氧化物半导体（CMOS）技术提供了具有缩小到22纳米的沟道尺寸的晶体管，从而实现超高速开关和数字处理性能。然而，在模拟域中，由于与其他替代方案相比，它们的增益 ** 和输出阻抗较低，因此性能可能受到限制。在本提案中，我们将设计、仿真、制造和测试一款高速、高分辨率ADC，用于高数据速率通信（即：1-5 Gsps）。在本提案的过程中，将研究 ** 以下挑战，并调查潜在的解决方案：a）** 制造技术、系统结构和处理单元与性能; B）** 新设计的ADC与MaxLinears当前信号链的兼容性。ADC的设计和实施具有 ** 上述方面，使Maxlinear的加拿大分部能够为加拿大社会带来进一步的发展和 ** 机会。
