This paper presents a receiver front-end circuit for wideband high-frequency ultrasound transducer applications. The front end consists of three main blocks, a low noise amplifier (LNA), a variable gain amplifier (VGA) and a biquad low pass filter (LPF). The receiver is specifically designed for polyvinylidene fluoride (PVDF) transducer imaging with a typical signal bandwidth of 10–60 MHz. To achieve...
A T-coil network can be implemented as a high order filter for bandwidth extension. This technique is incorporated into the design of the input matching and output peaking networks of a low-noise amplifier. The intrinsic capacitances within the transistors are exploited as a part of the wideband structure to extend the bandwidth. Using the proposed topology, a wideband low-noise amplifier with a bandwidth...
