Differential CMOS Sub-Terahertz Detector with Subthreshold Amplifier

We propose a differential-type complementary metal-oxide-semiconductor (CMOS) sub-terahertz (THz) detector with a subthreshold preamplifier. The proposed detector improves the voltage responsivity and effective signal-to-noise ratio (SNR) using the subthreshold preamplifier, which is located between the differential detector device and main amplifier. The overall noise of the detector for the T...

Implementation of a Low-kickback-noise Latched Comparator for High-speed Analog-to-digital Designs

In traditional comparators especially for ADCs, one serious problem is the kick back noise, which disturbs the input signal voltages and consequently might cause errors at the outputs of the ADCs. In this paper, we will work on a novel ultra low-power rail-to-rail CMOS latched comparator with very low kickback noise for low to medium speed ADCs. This comparator adopts a preamplifier followed by...

A Micropower CMOS Preamplifier for Cochlear Implant System

This paper proposes a CMOS low-power low-voltage microphone preamplifier for a cochlear implant system. The proposed preamplifier using the Flipped Voltage Follower Current Sensing (FVFCS) technique to achieve low voltage, low power consumption. The proposed circuit was designed and simulated using a 0.35 m CMOS process. Simulation results showed that the preamplifier can achieve 22-dB voltage ...
