“…There are great choices for TIQ comparators and for how to select them to apply in flash ADCs, which can be found in [ 4 ]. Take articles [ 5 , 6 , 7 , 8 ] as examples, which all discuss this structure when constructing flash ADCs. This brings a great advantage in power and spatial efficiency.…”

This paper presents a low-area 8-bit flash ADC that consumes low power. The flash ADC includes four main blocks—an analog multiplexer (MUX), a comparator, an encoder, and an SPI (Serial Peripheral Interface) block. The MUX allows the selection between eight analog inputs. The comparator block contains a TIQ (Threshold Inverter Quantization) comparator, a control circuit, and a proposed architecture of a Double-Tail (DT) comparator. The advantage of using the DT comparator is to reduce the number of comparators by half, which helps reduce the design area. The SPI block can provide a simple way for the ADC to interface with microcontrollers. This mixed-signal circuitry is designed and simulated using 180 nm CMOS technology. The 8-bit flash ADC only employs 128 comparators. The applied input clock is 80 MHz, with the input voltage ranging from 0.6 V to 1.8 V. The comparator block outputs 127 bits of thermometer code and sends them to the encoder, which exports the seven least significant bits (LSB) of the binary code. The most significant bit (MSB) is decided by only one DT comparator. The design consumes 2.81 mW of power on average. The total area of the layout is 0.088 mm2. The figure of merit (FOM) is about 877 fJ/step. The research ends up with a fabricated chip with the design inserted into it.

In this paper, a novel and simple multi-bit quantizer based on the threshold inverter quantization (TIQ) approach is presented for use in sampled-data circuits. The key part is a front-end signal conditioning circuit with the aid of the interpolation technique that makes it possible to realize a rail-to-rail input range operation over the conventional threshold inverter-based quantizer circuits while maintaining the benefits of the TIQ structure without employing any analog-intensive circuits such as current sources or amplifiers, thus achieving a digital-compatible implementation. Simulation results in TSMC 90-nm CMOS technology at a power-supply voltage of 1[Formula: see text]V confirm the efficient performance of the proposed circuit.
