Dickson voltage multiplier with 1 to 6 stages for dual-band rectifiers (2.45/5.8 GHz) with low input power
This paper presents the design of highly efficient rectifiers that can operate
at WiFi frequencies (2.45 GHz and 5.8 GHz) and match low input power.
The designed dual-band rectifiers use multi-stage dickson voltage multipliers
(DVM) (from 1 to 6…

One to many (new scheme for symmetric cryptography)
Symmetric cryptography will always produce the same ciphertext if the plaintext and the
given key are the same repeatedly. This condition will make it easier for cryptanalysts
to perform cryptanalysis. This research introduces a one-to-many…
