The circuit can be used as an extension shield for Arduino or microcontroller (MCU) or TTL/CMOS signal generator. PWM-based digital-to-analogue converters (DACs) ... Circuit diagram of PWM-to-analogue ...

Back in 2002, Elektor presented a DIY in-circuit capacitor tester circuit. Do you have a need to find ... This signal is divided in IC2.A which in fact constitutes our bipolar 100-KHz test signal ...

This paper describes CMOS circuits generating arbitrary chaotic signals. The proposed circuits implement discrete-time continuous-state dynamics by means of analog processing in a time domain.
