This paper examines a new architecture that combines super regeneration and time-based signal processing concepts to implement frequency-to-time conversion. The proposed structure can also be used to perform LC-tank oscillators testing by using simple and low-resolution digital circuits. Its front-end consists of two cross-coupled oscillators, triggered in time by two step-like signals with a time...
Implantable biomedical devices such as sensors and neurostimulators require a near-field inductive link to transmit power wirelessly. However, the near-field induced voltage is usually much larger than the compliance of low-voltage integrated circuit technologies. Thus most integrated power recovery approaches limit the induced signal to low-voltages with inefficient shunt regulation, or voltage clipping...
In this paper, we describe a 0.18 mum CMOS capacitive sensor for microfluidic applications. This sensor features an interface circuit, which is incorporated with a calibration circuitry. We present the design and thereafter simulation and experimental results in the support of discussed issues throughout this paper. The proposed interface circuit offers the advantage of low complexity as well as sub...
The design of a dual-source power scavenging and management system for ultra low power wireless medical applications is presented. Power scavenging is achieved by harvesting energy both from solar (primary) and RF power (secondary) sources. Depending on the available energy, the system can supply 1-2mW of power to a wireless device, with up to a 50% duty cycle. A radio-triggering based technique is...
