Latest Patents

One of Jianguo Yu's latest patents is a common-emitter amplifier with unilateral pre-embedding inductors. This invention includes an input matching circuit, a first-stage amplification circuit, a first-stage interstage matching circuit, a second-stage amplification circuit, a second-stage interstage matching circuit, a third-stage amplification circuit, and an output matching circuit. The design allows an input signal to sequentially enter the bases of common-emitter transistors across multiple stages, amplifying the signal progressively. The amplifier is specifically configured to introduce interstage staggered tuning, which expands bandwidth and addresses narrowband issues. The unilateral pre-embedding inductors are designed to reduce the required value of the parallel embedding inductor, simplifying the implementation of transmission lines.

Another notable patent by Yu is a pulse width control device and method, which includes a first monostable multivibrator that generates a negative pulse of a preset width and a second monostable multivibrator that generates a positive pulse of another preset width. This device also features an inverter and a flip-flop that work together to produce a synchronization pulse with a width between the two thresholds. This innovation is particularly useful in inkjet printing devices.
