Filed:

Feb 15, 2001

Appl. No.:

09/785081

Inventors:

Reed Irion - Austin TX, US
Hon Yee - Austin TX, US
Prahalad Vasudev - Austin TX, US
Sheela Vasudev - , US

International Classification:

H04B001/26

US Classification:

455/325000, 455/323000, 455/313000

Abstract:

Several embodiments of a block downconverter using a SBAR bandpass filter in a superheterodyne receiver are disclosed. The block downconverter is coupled to receive a radio frequency input that includes a target region. The block downconverter is configured to produce a selected one of an overlapping plurality of portions of the target region as an intermediate frequency (IF) block having a fixed center frequency. Furthermore, the block downconverter includes a semiconductor bulk acoustic resonator (SBAR) filter that operates as an IF filter.

Abstract:

This disclosure provides systems and methods for delivering a neural stimulation pulse. A neural implant device can include an energy harvesting circuit configured to receive an input signal and generate an electrical signal based on the received input signal. A diode rectifier in series with the energy harvesting circuit can rectify the electrical signal. The energy harvesting circuit and the diode rectifier can be encapsulated within a biocompatible electrically insulating material. A neural electrode can be exposed through the biocompatible electrically insulating material. The neural electrode can be configured to deliver a neural stimulation pulse. The neural implant device can have a volume that is less than about 1.0 cubic millimeter.
