A timer-controlled doorbell device has been developed using two 555 timer ICs in monostable mode, combined with a relay ...

To prove the advantages of such a system, the functionality of key circuit blocks is experimentally demonstrated. The characteristic properties of cryo-CMOS are exploited to design a noise-canceling ...

Symbolic circuit analysis is concerned with analytical construction of circuit response in the frequency (or time) domain, for which an efficient data structure is required. Recent research has ...
