Low Power and Wide Gain‐Range Mixer Using Current‐Bleeding Variable‐Gain Amplification

Microwave and Optical Technology Letters, Volume 68, Issue 4, April 2026.
ABSTRACT This paper presents a mixer with low power and a wide gain‐range using a current‐bleeding variable‐gain amplifier (VGA) technique. The proposed 2.4‐GHz mixer controls the conversion gain by replacing a conventional current‐bleeding stage with the VGA while maintaining the low‐power function of current‐bleeding.

Pulmonary Transit Time Can Be Accurately Quantified From Non‐Arterial Input Function Series in First‐Pass Cardiac Perfusion MRI

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2207-2213, April 2026.
ABSTRACT Purpose Previous studies suggested that arterial‐input‐function (AIF) images are necessary to avoid signal saturation for pulmonary transit time (PTT) measurements. This study challenges that notion by investigating whether PTT can be accurately measured using blood pool signals from myocardial enhancement (non‐AIF) images during resting first‐
