Astable multivibrator circuit

Clean black-on-white electronic schematic of an astable multivibrator built around a single switching block shown as a triangular operational amplifier symbol. The op-amp includes labeled positive and negative input polarity marks. A resistor-capacitor timing network connects between the output and an input node, with one parallel-plate capacitor symbol and resistor symbols shown as zigzag timing resistors. A positive-feedback resistor divider is connected to the op-amp input to establish the astable oscillator action. Include a clearly indicated output node representing a square-wave output. Overall style is simplified, compact schematic line art with standard circuit symbols.
