“…However, the sampling rate is very small (50MS/s). In [34], although the proposed VTC achieves a better dynamic range of 400mV, the power consumption of this design is relatively high (3.35mW). In [35], a fully digital time-based ADC is proposed to reduce the chip area at which the power consumption is reduced to 380μW.…”

Analog to digital converter (ADC) represents the link between the real world represented by real time analog signals and the digitized world represented by digital integrated circuits. The performance of the ADC depends on some important parameters such as resolution, sampling frequency, Signal-to-Noise Ratio (SNR), Power consumption and Figure- Of-Merit (FOM). This paper introduces a brief discussion of the most common ADC architectures. More detailed discussion on time-based ADCs is introduced and recent architectures introduced by researchers are presented and compared with each other in terms of linearity error, resolution, and power consumption. Moreover, a comparison survey is presented on the most popular commercial ADCs. The data used in the survey are taken for about 1500 commercial ADCs from major integrated circuits companies such as Texas Instruments and Analog Devices. The aim of this paper is to give a detailed comparison on the most common ADCs to help researches to choose the best architecture that fits their desired application and to draw researchers' attention towards time-based ADCs as they proved a promising performance improvements compared with other ADCs architectures in many applications such as software radio receivers.

“…A lot of research is done to improve the performance of the VTC circuit. Circuits in [16] and [26][27][28][29][30][31][32][33][34][35] are proposed to overcome the previously mentioned limitations of the conventional VTC circuit. In [16], a linearization circuit is proposed to achieve a maximum linearity error of 2%.…”

Beras merupakan bahan makanan pokok bagi sebagian besar masyarakat Indonesia. Konsumsi beras pada tahun 2018 mencapai 13,81 juta ton [1]. Pada umumnya beras ditanak menggunakan penanak nasi yang saat ini umum dipasaran. Tetapi karena persiapan yang dilakukan untuk menanak nasi cukup memakan waktu, membuat banyak orang malas untuk melakukannya. Karena untuk menanak nasi pengguna harus melakukan banyak proses. Mulai dari menuangkan beras dan air pada panci, lalu memasukannya pada penanak nasi hingga menekan tombol mode warm menjadi cook yang semuanya masih dilakukan secara manual. Sehingga diperlukan rancangan suatu sistem baru pada penanak nasi saat ini. Dalam sistem baru yang dirancang, pengguna dapat mengatur banyaknya beras yang ingin dimasak dengan pilihan yang bervariasi, melakukan pengisian beras dan air secara otomatis, memantau kapasitas beras dan air yang tersedia , sekaligus dapat memasak nasi secara otomatis di lokasi manapun selama smartphone terhubung dengan internet. Dari hasil pengujian sistem, diperoleh bahwa sistem dapat bekerja dengan sangat baik dengan tingkat keberhasilan mencapai 96,4% dari 54x pengujian.

“…However, the maximum linearity error is 2.1% and the modified circuit operates at a low clock frequency of 50 MHz. In Reference [11], a modified VTC is introduced to increase the linearity but the power consumption of this design is high (3.35 mW), and the input dynamic range is limited to 400 mV. In Reference [12], a fully digital time-based ADC is proposed to reduce the chip area at which the power consumption is reduced to 380 µW but still relatively high.…”

Time-based analog-to-digital converter is considered a crucial part in the design of software-defined radio receivers for its higher performance than other analog-to-digital converters in terms of operation speed, input dynamic range and power consumption. In this paper, two novel voltage-to-time converters are proposed at which the input voltage signal is connected to the body terminal of the starving transistor rather than its gate terminal. These novel converters exhibit better linearity, which is analytically proven in this paper. The maximum linearity error is reduced to 0.4%. In addition, the input dynamic range of these converters is increased to 800 mV for a supply voltage of 1.2 V by using industrial hardware-calibrated TSMC 65 nm CMOS technology. These novel designs consist of only a single inverter stage, which results in reducing the layout area and the power consumption. The overall power consumption is 18 μW for the first proposed circuit and 15 μW for the second proposed circuit. The novel converter circuits have a resolution of 5 bits and operate at a maximum clock frequency of 500 MHz.
