This thesis describes the design and implementation of an analog-to-digital converter (ADC)
taking an uncommon two-step approach: a voltage-to-time converter (VTC) converts the …

We present the concept and some implementations of time-based analog-to-digital
converters (TB-ADCs). The TB-ADC employs a fundamentally different architecture from the …

Due to technology scaling, the design of the conventional-type analog-to-digital converter
(ADC), which uses an operational amplifier as one of its building blocks, becomes more …

This paper presents the architecture of a high-speed time-based Analog-to-Digital Converter
(ADC) based on voltage-to-time and time-to-digital conversion. A tunable Time-to-Digital …

We present a first order analog-to-digital converter with time-variant window. If a DC input is
applied, the converter outputs a binary sequence until the internal state enters into the …

In this paper, a time-domain analog-to-digital converter (ADC) using time-to-digital converter
(TDC) is presented. The use of TDC in ADCs is a promising technique for future scaled …

Digital design is the driving force for the rapidly emerging deep submicron CMOS
technologies. As CMOS processes are typically getting more and more optimized for the …

As communication speeds have increased, high speed and resolution analog-to-digital
converters (ADCs) have become necessary. ADCs have traditionally relied on comparing an …

A novel 0.13 mum CMOS integrated linear voltage to pulse delay time converter (VTC) is
proposed. The VTC architecture uses current starved inverters where the inverter delay …

Existing implementations of time-to-digital converters are based on the use of reference
clocks. In the paper, a new method of clockless time-to-digital conversion (TDC) is proposed …
