This paper presents low-voltage pseudo differential pair operational transconductance amplifier (OTA) circuit designed and simulated in 130 nm CMOS technology. The imperialist competitive algorithm (ICA) is used to optimize the DC gain, common-mode rejection ratio (CMRR), and power dissipation of the presented OTA. The cost function of ICA is evaluated in(More)
This paper presents the design and simulation of the front-end low power transmitter for wireless sensor network application. The transmitter features simple circuitry with circuit techniques that reduce the power consumption and gives higher efficiency. The used modulation scheme is a modified version of ASK with better continuity to make it eligible for(More)
This paper presents a low power, high data rate transceiver for passive RFID tags. Asymmetric communication link between the reader and the tag was employed to overcome the passive systems' power constraints while providing higher data rates. For the uplink, a low power, digital Impulse Radio Ultrawideband (IR-UWB) transmitter was employed to send large(More)
