1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

This article presents a high-frequency application-specific integrated circuit (ASIC) transceiver for an ultrasound imaging system designed with a focus on low complexity. To simplify the design, it employs a conventional Class-D power amplifier structure for the transmitter (TX) and a resistive feedback transimpedance amplifier (TIA), which consists of a common-source amplifier followed by a source follower for the receiver (RX). Through careful optimization, the RX achieves a measured transimpedance gain of 90 dBΩ and an input-referred noise of 5.6 pA/√Hz at 30 MHz while maintaining a wide bandwidth of up to 30 MHz for both the TX and RX. The power consumption of the TX and RX is measured to be 7.767 mW and 2.5 mW, respectively. Further acoustic performance, assessed using an annular capacitive micromachined ultrasonic transducer (CMUT), showed a 1.78 kPa peak pressure from a 20 V pulser and confirmed the full bandwidth compatibility of the CMUT's bandwidth. The ASIC transceiver has been fabricated using a 0.18 μm HV bipolar-CMOS-DMOS (BCD) process.
