Abstract The paper proposes an advanced exclusive‐OR (XOR) design using a non‐stacked symmetric structure based on complementary pass transistor logic (CPL) for high‐speed applications. The proposed XOR adopts a non‐stacked structure where a

This paper describes a voltage-mode transmitter that supports both non-return-to-zero (NRZ) and four-level pulse amplitude modulation (PAM4) signal transmission. A 2-tap feed-forward equalizer (FFE) is implemented with PAM4 equalization logic consist

We propose a CMOS image sensor with a dedicated low-power imaging mode and low-power integrated transmitter. The proposed CMOS image sensor selectively operates in dual mode: a high-quality mode with a 1.5 V supply voltage of readout circuits to achi

An 8-bit switched-capacitor multiply-and-accumulator (MAC) in 65nm CMOS is presented. Based on a cascaded low-power ring-amplifier-based switched-capacitor DACs, the MAC circuit features a programmable accumulation length in MAC computation. Fabricat

This paper describes a voltage-mode transmitter that stacks independent non-return-tozero (NRZ) and four-level pulse amplitude modulation (PAM4) drivers for dual channels. The stacked structure can improve the transmitter's power efficiency owing to

An output capacitor-less low-dropout (OCL-LDO) regulator with a wide range of load currents is proposed in this study. The structure of the proposed regulator is based on the flipped-voltage-follower LDO regulator. The feedback loop of the proposed r

Flexible and thin displays for smart devices have a large coupling capacitance between the sensor electrode of the touch screen panel (TSP) and the display electrode. This increased coupling capacitance limits the signal passband to less than 100 kHz

We propose a dual-channel interface architecture that allocates high and low transition-density bit streams to two separate channels. The transmitter utilizes the stacked drivers with charge-recycling to reduce the power consumption. The direct curre
