Square-wave generator circuit

Abstract

The invention relates to the field of design of integrated circuits, in particular to a square-wave generator circuit. The square-wave generator circuit is connected with a direct current power supply and comprises a first current mirror, a second current mirror, a first phase inverter, a second phase inverter, a third phase inverter, a fourth phase inverter, a capacitor C1 and an capacitor C2. Compared with the current general square generator circuit, the novel square-wave generator circuit disclosed by the embodiment of the invention and designed by a CMOS (Complementary Metal Oxide Semiconductor Transistor) process has the advantages of simple structure, fewer specific elements and greatly reduced static power consumption, and can be used for producing square waves with adjustable period and duty ratio as required by utilizing the switching characteristics of the phase inverter.

Description

technical field [0001] The invention relates to the field of integrated circuit design, in particular to a square wave generator circuit. Background technique [0002] A square wave is a non-sinusoidal waveform that usually appears in the electronic field and signal processing, and a square wave is a control signal for many electronic systems. The square wave is generally the same, but the amplitude, period, and duty cycle of the square wave vary according to the specific application environment. [0003] The existing square wave generator circuit generally requires two comparators, two high and low fixed levels, and several digital logic gates. Therefore, the circuit structure of the entire square wave generator is relatively complicated, and a certain amount of static power consumption is required. In fact, whether it is integrated circuit design or other electronic system design, under the premise of ensuring the function and performance, the simpler the structure, not o...
