Time-based-Analog-to-Digital-Converter (TADC) is an important block in various applications that require higher resolution and lower power consumption compared to the conventional ADCs at scaled CMOS technologies. In time-based ADCs, the input voltage is first converted into a pulse in time by using a Voltage-to-Time Converter (VTC) circuit, and then the pulse is converted to a digital output by using...
A new differential Voltage-Controlled Delay Unit (VCDU) is proposed. The VCDU converts an input voltage into a pulse delay, and delivers it to a Time-to-Digital Converter (TDC) which outputs a digital word. Both circuits form a Time-Based Analog-to-Digital Converter (ADC). In scaled CMOS technology, the Time-Based ADC is a substantial block in designing Software Defined Radio (SDR) receivers, as it...
Time-Based Analog-to-Digital Converter (ADC) becomes the key of the new era of scaling CMOS technology. It provides a lower power and area than conventional ADCs. These improvements urges the Time-Based ADC to overcome Software Defined Radio (SDR) receivers' challenges and to be a dominant module in designing them. Such an SDR receiver can adapt itself automatically to deal with the desired bandwidth...
Time-based ADC is an essential block in designing software radio receivers because it exhibits higher speed and lower power compared to the conventional ADC, especially, at scaled CMOS technologies. In time-based ADCs, the input voltage is first converted to a pulse delay time by using a voltage-to-time converter (VTC) circuit, and then the pulse delay time is converted to a digital word by using...
Voltage-to-Time Converter (VTC) circuit is considered one of the essential blocks in the design of Time-based Analog-to-Digital Converters (T-ADCs). T-ADC is a promising candidate for Software Defined Radio (SDR) receivers that require wide band and high resolution ADC circuits. T-ADC circuits provide higher speed and lower power dissipation compared to conventional ADCs. The proposed design methodology...
