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 …

A 100-kS/s time-domain analog-to-digital converter (TDADC) with successive approximation
register architecture provides 8.3 effective bits. The time-domain comparator of the TDADC …

A second-order, single loop ΔΣ time-to-digital converter (TDC) is presented in this letter. The
proposed TDC uses two differential current-controlled oscillators as phase domain …

A time-to-digital converter (TDC) is proposed to replace the multi-bit quantizer and the multi-
bit feedback DAC of traditional voltage-mode ΣΔ modulator. Since time-mode systems …

Sigma-delta modulator based DACs are simple circuits with low accuracy requirements in
their analog components. However, their signal bandwidth is limited by speed constrains …

A time-to-digital converter (TDC) employs a phase-reference second-order continuous-time
delta-sigma modulator to achieve high resolution and low power. The modulator operates …

This brief presents an all-digital first-order 1-bit ΔΣ time-to-digital converter (TDC) using a
time-mode signal processing approach. Time integration is performed using a bidirectional …

Two two-step cyclic time-domain analog-to-digital converters (TADCs) in a 0.18-μm CMOS
process are presented. The proposed TADC uses a voltage-to-time converter (VTC) with a …

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 …

In this paper, a bandpass analog-to-digital converter (ADC) based on time-interleaved
oversampled ADC is introduced. Unlike previous delta-sigma bandpass ADCs that require …
