Abstract :
This paper presents a design of on-chip voltage generator for applications in battery-less low voltage transceiver. The supply voltage for this on-chip voltage generator is obtained from mutual inductive coupling through radio frequency (RF) electromagnetic field which is able to generate 150 mV peak voltage. This on-chip voltage generator is used to generate a supply voltage for a low voltage low power transceiver. Simulation results showed that it is able to give a constant voltage of 1.8 V with 30 muA of current from an input of 150 mV peak voltage. This chip is realized using a CMOS 0.18 mum process.
