This paper presents a custom-designed single-cable readout IC for the reception of the broadband photoacoustic (PA) signal in intravascular photoacoustic (IVPA) imaging. The readout IC is intended for direct integration behind a broadband polyvinylidene fluoride (PVDF) transducer in an IVPA catheter tip to match the impedance between the small PVDF element and the connecting cable. The capability of the readout IC to work with a single cable that combines the output signal and the power supply ensures the mechanical flexibility of the IVPA catheter. Electrical measurements show that the readout IC provides a flat frequency response from 1 MHz to 20 MHz with a 6 mA external current supply. The acoustical measurements involving the readout IC and the PVDF transducer demonstrate a 60 dB dynamic range, a sensitivity of 3.8 μV/Pa at 2.25 MHz, and a broad receiving bandwidth from 2 MHz to 15 MHz.
