Abstract: The technology described herein is related to a two-phase deployment-initiated wakeup mechanism for a body-mountable electronic device. During a first phase of the two-phase wakeup mechanism, a motion sensor detects an acceleration event indicative of deployment of the device onto the body of the user. During a second phase of the two-phase mechanism, control circuitry can be adapted to be enabled by the acceleration event. Once enabled, the control circuitry can verify that the device has been launched onto the body of a user via a deployment applicator in which the device is retained until deployment. Once verified, the control circuitry can wake up the body-mountable electronic device by transitioning the device from a sleep state to a functional (or operational) state.

Abstract: Amplifiers with improved isolation are disclosed. In an exemplary design, an apparatus (e.g., a wireless device, an integrated circuit, etc.) includes an amplifier having a gain transistor, first and second cascode transistors, and a shunt transistor. The gain transistor receives an input signal and provides an amplified signal. The first cascode transistor is coupled between the gain transistor and an intermediate node and receives the amplified signal. The second cascode transistor is coupled between the intermediate node and an output node and provides an output signal. The shunt transistor is coupled between the intermediate node and circuit ground. The first and second cascode transistors are enabled to provide the output signal. The shunt transistor is (i) disabled when the cascode transistors are enabled and (ii) enabled to short the intermediate node to circuit ground when the cascode transistors are disabled.
