In one example in accordance with the present disclosure, an imaging device is described. The imaging device includes an array of transducers. Each transducer includes an array of piezoelectric elements. Each piezoelectric element transmits pressure waves towards an object to be imaged and receives reflections of the pressure waves off the object to be imaged. The imaging device also includes a transmit channel per one or more piezoelectric elements to generate the pressure waves and a receive channel per one or more piezoelectric elements to process the reflections of the pressure waves. The number of channels are selectively altered to control parameters such as power consumption and temperature.

Imaging devices with selectively alterable characteristics

A system includes a switched capacitor circuit and a stabilizing circuit. The switched capacitor circuit receives a reference voltage from a reference node, transitions from a first state to a second state, and draws or supplies a switched capacitor charge from or to the reference node in response to transitioning from the first state to the second state. The second state is a function of the first state, an input of the switched capacitor circuit, or a combination of both. The stabilizing circuit stabilizes the reference voltage by supplying or drawing a stabilizing charge to or from the reference node based on the first and second states of the switched capacitor circuit.
