What are the procedural assignments in Verilog HDL?

In Verilog HDL, there are two procedural assignments, blocking and nonblocking.

What are the advantages of a conversion element made using the eddy current effect?

The advantages of the conversion element made by the eddy current effect are: high sensitivity, simple structure, strong anti-interference ability, no influence of oil and other medium, and non-contact measurement.

What are the main characteristics of photocells?

The basic characteristics of photocells are: volt-ampere characteristics, photoelectric properties and spectral properties.

What are the new semiconductor devices that Zetex focuses on?

Zetex focuses on adapting to these unique new semiconductor devices, including bipolar transistors, MOSFETs, Schottky diodes, current monitoring devices, and low-power current regulators.

What is the piezoresistive effect?

After the single crystal silicon material is subjected to stress, its resistivity changes significantly. This phenomenon is called piezoresistive effect.

Briefly describe the logic function of the CMOL circuit?

The logic function of the CMOL circuit mainly depends on the underlying CMOS circuit unit, which consists of an inverter and two pass transistors, where the pass transistors are used for the input and output of the CMOS unit circuit.
Two-pass transistors are connected to the output nanowire and the input nanowire, respectively, and are used as pull-up or pull-down resistors.
The “OR” logic is realized between the upper two layers of nanowires through molecular devices, and the bottom CMOS single-channel unit realizes “NO” logic, so the CMOL circuit only realizes a single NOR logic function.
In the CMOL circuit, through the two-layer nanowire array and the underlying CMOS inverter circuit, the realization of the circuit logic function is very simple.
As long as the molecular device between the output nanowire of the output unit participating in the NOR logic operation and the corresponding input nanowire is in the “ON” state, the NOR logic between the corresponding CMOS units can be realized.
