Description: An elegant design incorporating an simple operational amplifier schematic with a unique PCB font

Description: A black background displays an electrical schematic diagram on the left, featuring an operational amplifier symbol in orange. Text elements 'VIN', 'VOUT', 'RF 2', 'RG', and 'F' are visible. To the right, bold white text reads 'I ONLY GIVE' above 'NEGATIVE FEEDBACK', separated by an orange line with a waveform.

Description: A schematic diagram of an operational amplifier circuit with input ('VIN') and output ('OUTPUT') labels. It features resistors labeled 'RF' and controls labeled 'GOUT'. To the right, large white text reads "I ONLY GIVE NEGATIVE FEEDBACK" with a stylized electrocardiogram waveform integrated into the word 'NEGATIVE'. The overall style is minimalist and technical.

Description: A split composition featuring an operational amplifier schematic on the left, with labels like VIN, VOUT, V, RF, RG, and ICT, and a bold white text statement 'I ONLY GIVE NEGATIVE FEEDBACK' on the right. A waveform is integrated into the text.

Description: A simple circuit diagram with two resistors labeled R1 and one labeled R2, connected to a diamond-shaped operational amplifier symbol denoted as 'OP-BP' with '+' and '-' inside. To the right, white text reads 'I ONLY GIVE NEGATIVE FEEDBACK' in three lines.

Description: A schematic shows an operational amplifier with input labeled 'VIN' and output labeled 'VOUT'. It includes feedback resistors labeled 'Rf' and 'Rg'. To the right, large white text reads 'I ONLY GI' followed by a stylized heartbeat wave integrated into the letter 'E'. Below, text reads '_NEGATIVE FEEDBACK_'. The background is black.
