Abstract EN
The CMOS Monolithic Active Pixel Sensor (MAPS) for the International Linear Collider (ILC) vertex detector (VXD) expresses stringent requirements on their analog readout electronics, specifically on the analog-to-digital converter (ADC).
This paper concerns designing and optimizing a new architecture of a low power, high speed, and small-area 4-bit column-parallel ADC Flash.
Later in this study, we propose to interpose an S/H block in the converter.
This integration of S/H block increases the sensitiveness of the converter to the very small amplitude of the input signal from the sensor and provides a sufficient time to the converter to be able to code the input signal.
This ADC is developed in 0.18 μm CMOS process with a pixel pitch of 35 μm.
The proposed ADC responds to the constraints of power dissipation, size, and speed for the MAPS composed of a matrix of 64 rows and 48 columns where each column ADC covers a small area of 35 × 336.76 μm2.
The proposed ADC consumes low power at a 1.8 V supply and 100 MS/s sampling rate with dynamic range of 125 mV.
Its DNL and INL are 0.0812/−0.0787 LSB and 0.0811/−0.0787 LSB, respectively.
Furthermore, this ADC achieves a high speed more than 5 GHz.
